Help!?

Jordyn
Ok. So i had my stillborn on dec 20th 6 weeks ago i was 18 weeks after i had her i bled for exactly 1 week then stopped occasional spotting brown here and there...i have yet to have a period and i know thats normal but i have been having alot of unprotected sex ttc again...i took a pregnancy test two days ago at 530pm and it gave me a faint positive...now i just took one with fmu and its so faint i think its bfn.i took an ovulation test also and its positive!? So im all screwed up in the head. Btw i am now 12 days late and ive used same brand of pregnancy test both times...no pregnancy symptoms really other than constipation and headaches occasionally and im always tired so idk how to pick up that as a symptom lol please help me
