So a couple weeks ago my SO and I had sex. We unfortunately didn't use protection & ive never used birth control. It was two days after I ovulated. He came inside of me but I took a shower and tried to push it out lol (that sounds gross) but a lot of it came out. I thought I'd be fine. So my period comes around and I'm late. It's been day 4 of my period and when it was suppose to start & still nothing. I took a test yesterday and this morning and both said negative. Could they be wrong? Is it too early? I need some insight ladies...HELP!
