ok no swimming and having sex twice the day your period started have nothing to do if can you be pregnant
you can get pregnant from precum. but if you did....you wouldnt have gotten your period. you could have spotted around that time but not a full blown period.
precum does contain sperm and ALWAYS use a condom!
you could take a test by now if your periods already off
Here's my opinion:
You're probably not pregnant if you started your period. If you started your period two days later, then it was probably too late in your cycle for you to be ovulating anyway. But don't use the calendar method (to calculate/estimate when you ovulate) to prevent pregnancy either. Some women ovulate more than once or later in their cycle.
Nausea from pregnancy is not an immediate feeling for most people; it usually occurs later, several weeks, into pregnancy.
My friends and I have a joke about this:
Q: You know what they call people who use the pull out method?
A: PARENTS!
Advice from an adult mother:
If you don't want to get pregnant, don't have unprotected sex. There are so many other things to worry about besides pregnancy (STDs) if you are having unprotected sex. If pregnancy is all you get from unprotected sex, then you're very lucky!
OK, that's my two cents, like it or not.
ALSO. We went swimming in a pool before having sex. I am not sure if this plays a part in my possibility of becoming pregnant.
In addition to the previous post. The day after my period started. I got a very upset stomach and vomited a couple of times. Then I got a fever and felt very dizzy. I am not sure if those are a signs that I am pregnant or just that I ate something bad and threw up. Or if the fever made me throw up. Does my vomiting and headache mean I'm pregnant? Right now (2 days after), I am fine.
