Okay still waiting for my blood tests to come back out did a pregnancy test and it was negative not sure what to think now.

Okay ladies need some advice feeling a little alone here, the last too months my periods have been late (this months period is still late) talked to me doctor and have to do blood work soon... the thing is I was irregular right up until I had my daughter then tried the pill and it messed up last month and I was told the effects are out of my system now, but my doctor did answer my question if because I was irregular before if I could go back to being irregular. Anyone else go through this? And side note this month I have had no pms symptoms
