How can you tell for sure that you’re not pregnant, besides a test?
Q: I’m a little paranoid when I have sex with my boyfriend. I mean, we’ve been together a long time, and we’ve been active for some time as well… I’m 19. I once thought that once you get your period, you know you’re “home free” so to speak, but you can get pregnant on your period as well. We are very careful, use condoms, and all of that stuff, I just want to be extra sure.How do you know for sure, besides a pregnancy test, that you’re not pregnant?
A: If you’re having your period normally and they are ‘proper’ periods, you are using brith control and have no other symptoms of pregnancy then you have very little reason to worry. usually the first didtinct sign of pregnancy is a missed period and if you’re having periods as normal it is unlikley you are pregnant, however the only other way of determining this for sure is to take a test
How long does it take to tell if you’re pregnant?
Q: I had sex with my boyfriend without any protection and I’ve been off the pill for a month now and he went inside me and all that good stuff. This was last night. If I bought a pregnancy test, how long does it normally take until results are accurate? Like, if I took one today am I going to test positive if I am?
A: 2 Weeks. I’m not kidding. It takes 24-48 hours for the sperm to travel into the uterus and up to the fallopian tubes. If an egg is present, it takes another 24 hours for a successful fertilization to occur (sperm meets egg). If an egg is not present, the sperm will hang out there and wait, up to five to seven days!, for an egg to be released. If a successful fertilization occurs, the fertilized ovum (pre-embryo/blastocyst) travels into the uterus. This takes a good solid week to week and a half to complete. Once in the uterus, the fertilized ovum attempts to implant in the uterus wall. This, too, can take several days. If implantation occurs (67% of the time, however, it will not and the fertilized ovum is expelled from the body), you can then consider yourself pregnant but it will take a few days for the hormone levels to be high enough to test positive.That is why you are typically advised to wait until the first day you miss your period. A typical Woman with a typical cycle ovulates 14 days after the first day of her last period. After that, it’s about another 2-3 weeks until her next period starts. If she doesn’t start, it’s a good indication that it’s time to test. You don’t become pregnant automatically upon ejaculation. Pregnancy is a process and the majority of the time it doesn’t work out.Best of luck!Peace,Jenn
Breastfeeding mommies, how do you tell if you’re pregnant or not?
Q: I’m being serious here. If your baby is exclusively breastfeeding, and you haven’t had a period yet, how can you tell? I know you have the same symptoms of pregnancy as always, but how do you tell the difference? Your breasts are already sore from feeding during the day, you’re already tired from taking care of a baby, you’re hungrier than usual. So many of the pregnancy symptoms get masked by the breastfeeding. I don’t think I’m pregnant, but I’m just curious how you tell without taking a pregnancy test and then finding out you’re three or four months pregnant. Any personal examples would be appreciated, too.
A: well i hope jessica whoever doesn’t want a zoo full of kids! I was breastfeeding my 8 month old daughter & got pregnant. Breastfeeding is NOT a form of birth, for your question: I was EXTREMELY tired before I actually knew I was pregnant. I was thirstier than usual because when you’re pregnant & breastfeeding at the same time, your body needs more fluids. I was craving alot of food I usually don’t care for & gained weight. I didn’t know for certain I was pregnant though, til i took a pregnancy test & they confirmed it w/my doc.
