What to do?

I'm just not sure what's going on with my cycle. I had a miscarriage the end of January and bleed for three  months until I had to do a round of the pill to get it to stop.   had my period right after the pill which was from the 20th-25th of May. Before the miscarriage I had a normal 28 day cycle. I have not had my period yet but haven't got a positive test. I'm not sure if I just need to wait or what.
