needing some advice: in early may I had a miscarriage.. June 4th I had a period that lasted 6 days.. now July 8th I still haven't had a cycle. we are still ttc but I took a test today and it was negative. I'm exhausted and my face is breaking out really bad. I'm wondering if this is a terrible pms or pregnancy. my cycles are always on track and my other 2 pregnancies tested positive at 2 days late. anyone else had this happen?
