It could be that the hormones are not strong enough to detect yet. When I missed my period I hardcore pmsed and then one day all my symptoms came to a complete stop. Also to be honest I didn't feel pregnant until the morning sickness started which was a couple weeks along. Also implantation bleeding does cause you to bled a little so that could possibly explain the blood. You could be pregnant and you might not be. If your concerned talk to your doctor. I hope this was helpful.
Sounds like pregnancy! Before I found out I was pregnant I had pink discharge come out ttoo so I thought I was about to start my period, but Nope! It was implantation bleeding. Plus 3 weeks after a late period? You should take a test, the result should be accurate by now.
Oh sorry, I read the last part , you already ttook some tests. Well it could just be a missed period, hormones changed, stress... And so on
ok thankyou in my eyes it could go either way. i guess i just needed an unbiased opinion. i appreciate you two taking the time to respond!
