so I had sex on July 2nd and my period was due on the 19th-ish. it says I'm 20 days late and I've taken 2 pregnancy tests. both have been negative but on the second one I feel as if I saw a faint line, but that was after the10 minutes of taking the test. I've been so nervous that I'm stressing myself out and I just want this to be over. my period is irregular and there have been times where I missed a month but I'm just very scared.
