I want to thank all of you for your responses! each one of them are very helpful.... I did fail to mention that I have had to run to the restroom... not to vommit but to pee...is this another early sign of 'early' pregnancy?
You cant go by symptoms.
Take a test about 14 days after unprotected sex. You can test 10 days after unprotected sex with a good, sensitive, test and first morning urine but this can be too early to test for some women.
you can start testing anytime. It is early so I would only use an early result test, however it's unlikely that you would get pregnant from that one encounter, only because you should have ovulated around the 22, for you to ovulate on the 29th that would have been a late ovulation for you - which CAN HAPPEN! I would guess that the symptoms you are feeling are from an impending period. Good luck and let us know what happens :)
It all depends on when you ovulate. Wait for your period to come and if it doesn't, take a pregnancy test with first morning urine. If you're not wanting children, I'd recommend birth control and/or condoms. The pull out method is NOT birth control and is very unreliable.
It is always possible to get pregnant when not on birth control. I beleive there are some tests out there that can tell you if you are pregnant up to 6 days before your next period is due. Other than that, you can wait to see if your period comes and if not, take a test then, and it is best to use your first morning urine because it is most concentrated then!
