i had sex for the first time about a week and a half ago. it was two days after my period, and the condom broke, but my boyfriend pulled out. we had sex again 3 days ago, and today i have horrible cramps and nausea. i should be ovulating sometime soon (plus or minus a day or two) could these symptoms be signs of pregnancy? or something else? the flu has been going around where i work. could i feel nausea from that and be experiencing cramps for a different reason? thanks!
