What is the most common cause of early miscarriage?

Q: Im 5 weeks pregnant, and my doctor said nothing will be done until i see the midwife, and that wont be until 12 weeks for my scan. He seemed to stress that at 5 weeks this is a very early pregnancy and it is very common to loose the baby from now to 12 weeks… I was a little shocked at how negative he was being to be honest as this is our first pregnancy and i was very excited before i saw the doctor. Now im wondering what could go wrong? why do so many pregnancies abort themselves before 12 weeks??

A: The most common cause of miscarriage from 1-12 weeks is chromosomal abnormalities of the egg. Every woman has approximately 20% of her eggs with a chromosome abnormality. If one of these abnormal eggs is fertilized, it will generally end in a miscarriage. There is nothing that the mother can do for a chromosomal problem, sadly a miscarriage will just happen.Things she can do to help keep her pregnancy healthy are: eating healthy foods, taking prenatal vitamins, drinking 8 glasses of water per day, getting plenty of rest and avoiding smoking and alcohol.

Depressed about miscarriage, I need advice?

Q: I just can’t seem to get my mind off of losing our baby. Its really been bothering me. I feel so lost and depressed.It could be a number of things. The first pregnancy test I took, it had 2 dark lines. The second one had dark lines, but a little less dark. The third one had a dark line and a faint line. Just to be sure, I went to the hospital to confirm it, and sure enough, the hospital test came out positive too. So, I’ve read a lot about the hCG hormone (the pregnancy hormone). I think the reason behind my fainter lines each time I tested is because my hormone levels were dropping. If that’s the case, then I will have to take hormone shots if I become pregnant again to keep the baby alive & healthy during pregnancy.Another thing. The doctor said my cervix was open. I don’t know if she meant it was open just during the miscarriage, or the whole time I was pregnant. If it was open the whole time I was pregnant, then once the baby got heavy enough, my cervix probably couldn’t bare the weight and the baby just dropped out. I know that sounds horrible, and I don’t mean it to be. I’m just thinking about all the possibilities of what could have happened.Yet another thing. Sorry if this is TMI, but I want to write out my honest feelings. Sexual intercourse has been known and is a common cause of miscarriages. Its not dangerous if its gentle, but if rough, it can cause the embryo to separate from the uterine wall and hemmorhage, causing a m/c. Sorry again if TMI, but I feel its my fault it happened.Another thing. Blood types. Mine is O+ and Josh’s is O-. Different RH factors can be a cause in miscarriages. If my body detects a negative RH factor, my body will find it as a foreign object and try to fight the off. So if thats the case, I will have to take shots during pregnancy to keep my body from expelling the embryo.Gosh, it can be litterally a number of things. This is just a few things I’ve thought about that might have caused my m/c. At this point, after three miscarriages, I’m starting to wonder if I can even carry a baby to term. I guess thats why Josh and I have to start going to a specialist to determine what the problem is. I hope its something that can be cured easily though; I would give anything to have my own baby. If we can’t, I guess we’ll just adopt. I know there’s a lot of babies out there that need a good home and loving family.It just depresses me to know that there are people out there who shouldn’t be parents having kids everyday. People that are into drugs, alcoholics, abusive people, people who don’t even want kids…yeah. That makes me sad. Josh and I are both clean people, and we genuinely tried to concieve a baby with no luck, and when there IS luck, we end up losing it.Anyhow, I guess thats my rant. I really had to get some of that stuff down before I went insane. Thanks for reading if you made it this far.Heather [Loves her little Angel] <3

A: Hi, first off i am so sorry for your losses, i too have suffered 3 miscarriages, all this year. 1st was a natural m/c at 5wks – blighted ovumn, 2nd missed m/c at 12wks, only detected at 12wk scan after previous early scans showing heartbeat, d&c required this time, 3rd was chemical pregnancy around 4-5wks. After my 2nd m/c i found out my bloodtype is O-, Rh-. You and your partners bloodgroups would not cause a m/c, this is only the case when the female is Rh- and the male is rh+. I know it is so hard to understnad why these things happen to good honest people like us and yet young kids or people who don’t want children can go on to have healthy pregnancies and healthy babies (at which don’t get me wrong i would never wish any ill-will on anybody). I got blood tests done after my most recent m/c in September, all of which came back normal, my doctor has just put it down to bad luck and the fact that i got pregnant so quickly after each m/c, not allowing my body/womb time to heal and repair itself. I just want you to know you are not alone, although i do know it feels like it sometime. I wish you all the best for the future and hopefully through time we will have children of our own, i am a firm believer in what’s meant to be will be and when it is our time it will happen.

what causes a chromosomal defect in a pregnancy which leads to miscarriage?

Q: Im 7 weeks pregnant and just found out that my baby has no heartbeat. The doctor also did blood tests and my HCG levels did not rise enough to be normal. They told me I will lose the baby. I’m just waiting for it to happen. Anyway, it is my first pregnancy so naturally Im concerned about future pregnancies as well. I heard that chromosomal defects are a common reason for miscarriage…any info on what causes that to happen?

A: Early miscarriages have many different reasons. Genetic components are only one reason, and most genetic issues are due to random errors in replication which are unrelated to anything traceable. One early miscarriage is not a reason to suspect that there is anything “wrong” with you, they happen rather frequently. It is estimated that all women have a miscarriage at some point in their lives, and as many as 1 in 4 pregnancies end in spontaneous early miscarriage. Many women just don’t know they were pregnant because it happens so early that they pass it off as a period. Sorry for your loss, good luck to you.
