Had sex a day after I ovulated and now my period has not shown up yet. Is it possible to get pregnant after ovulation? My periods are usually very regular and either show up a day early or right on time... has anyone ever been in this boat and been pregnant? I'm not having period or pregnancy symptoms. Genuinely I cramp and such when my period is on it's way and I haven't had any of that. What's y'alls thoughts? I did take a test, but discovered that it was expired, so I don't trust it and will be getting new tests today after work.
