3DAYS LATE???

Eve

I’ve been cramping for 2 weeks now I took a pregnancy test and got a faint positive at 8DPO but then took another one at 10 DPO and it still faint probably a little lighter then before. I went to the hospital 2 days ago because of a small ovarian cyst and they did a pregnancy test and came out negative... I am now 3 days late from my period Idk what’s going on? Is it possible to get a positive now after missed period or is something else going on?? I’m so confused they didn’t even draw an blood at the hospital even just for check. Only told me to do repeat ultrasound in 6-8 weeks to check the small cyst
