When did i conceive i got my period february 4 , i started to feel pains on my side 2/18 i did have sex , then i had sex on 2/22 another partner help ?

Very dicey situation: Based on the information you provide, and if your periods are typically regular ... about 28 days apart ... it is more likely that you conceived on 2/18. Unfortunately, I presume you were not using contraception either time. You will have to wait and see if you ARE pregnant (test 1 week after missed period). If so, relationship with each will have to be your guide.Talk to trusted friend/counselor

Hard to know.: if you had unprotected sex with two separate partners four days apart, it will be difficult to judge which is the father. You could probably tell which was closer to the date of ovulation, but you'd still not be certain, because they are both within a fairly fertile period for you. If it comes down to it, you could do genetic testing after the baby was born. Good luck.
