Unsure

Went off pill in July but just decided to TTC early March. Even after pill my cycle was usually around 30 days give or take a couple days. Last month was extremely stressed from work and cycle lasted 36 days. I’m at 36 days now... not stressed in the least but no AF yet! Got a BFN Thursday and a BFN this morning even though I woke up out of a dead sleep to run to bathroom to throw up... ended up hanging around the toilet feeling nauseous but never did throw up! Feeling frustrated and wondering what to do? Thoughts??
