pregnancy ?

Korie

I’m going to start with the fact that for a whole week almost a month ago me and my fiancé were having sex unprotected. Last week I woke up went pee and I bled a lot got in the tub and was bleeding as well so I assumed I had my period . It was bright red blood . I put on a pad then check it later, nothing. Same thing the rest of the day no blood. Then I discussed with some with someone I trust about me having sex a few weeks ago and that I have been nauseous and tired a lot. So I took a pregnancy test 5 days before my period (5 days ago) with a clear blue test . I waited five minutes no pregnancy like then 10 mins later I noticed there was a second line. And I’ve posted it people think it was an evap line. I took one the next day negative . I was supposed to get my period today and it didn’t come and I have had any of my usual signs of my flow coming on how I usually do like really bad cramps lower back pain, etc. so I need opinions and thoughts. I’ve never been pregnancy or issues with my period so I’m not very sure of what is going on with my body. I do want a child but I don’t want to get my hopes up.
