Nothing is making sense. Help!!

I was on the pill for 2 months, due to PCS (pelvic congestion syndrome) I got my period the first time, and then the second month I didn’t get one. At this point I’m 20 days late for my period. I stopped taking the pill Monday, and I still haven’t had any type of withdrawl bleeding. Just some cramping. Any tests I took when my period was originally late, were negative. And at this point I’m so overly confused. 🙁 Currently trying for a baby. Not going all the routes but just letting things happen. Please help a woman out.
