To be technically correct, it's called an "Ectopic" pregnancy, which occurs when a fertilized egg begins to grow in one of the fallopian tubes that normally transport an unfertilized egg from the ovary to the uterus rather than descending into the uterus and attaching to the Uterus wall/lining.
As for your question, a man who has had a vasectomy is by definition sterile and cannot impregnate a woman (assuming that the vasectomy was successful, of course).
Vasectomy involves cutting and cauterizing or clamping the tubes that transport sperm from the testicles, so after this procedure has been performed, no sperm will be present in the ejaculate that comes from the man during orgasm.
Normally, only a few small drops of the ejaculate come from the testicles anyway, the rest is from the prostate so there is no noticeable difference in ejaculate from vasectomized men.
For several weeks following a vasectomy, Birth Control measures should still be used to prevent and remaining sperm from potentially causing pregnancy, but that sperm wouldn't cause an ectopic pregnancy any more than other sperm.
Most often missed periods occur during pregnancies.
happens in only about 1-2% of pregnant women. But multi-fetal pregnancies occur far more often in women using fertility drugs.
I have had two pregnancies including a set of twins and had heartburn with neither. I have a friend who has got through a bottle of Gaviscon a week from 16 weeks with all four of her pregnancies. It depends.
No
In the US about 750,000 teens from 15-19yo get pregnant. 2/3 of all teen pregnancies occur among teens age 18-19yo.
There is no 100% foolproof method of birth control. Pregnancies occur on all methods. Mirena is one od the most reliable, but is not perfect.
An ectopic pregnancy is estimated to occur in up to 1 out of every 50 pregnancies.
70%
There have been documented cases of 10 month pregnancies although not typical they do occur. Yes it is possible. You may have ovulated later than thought.
"If you have had a tubal ligation bilaterally, then you can't become pregnant." This answer is not true at all. The failure rate of a ligation is small in comparison to other methods of birth control, but pregnancies do occur.
Hyperemesis, or extreme nausea and excessive vomiting, occur in about 1% of pregnancies
