Late period & Spotting

Caylin

Hey ladies. So I know the app doesn’t really specifically know when you ovulate but we had sex multiple times during my “ovulation window” I have had no symptoms of either my period or pregnancy that I noticed. I have been completely exhausted this week and have had a headache all week. So on Monday I had just spotting on the toilet paper of like brown blood with some cramping for maybe an hour then it stopped and then a very small amount again on Tuesday. I did a pregnancy test on Wednesday and it was faintly positive but there. Thursday I tested again it was clearly negative. It’s now Saturday early morning and I am now 4 days late… what should my next step be?
