Need some answers

So a couple months ago i had a cyst rupture right next to my left ovary. I was in the hospital and they put me on a hormone thing to balance everything out cuz i was bleeding for 8 1/2 weeks straight. Ever since i went back to normal my body has been doing something funky. My periods are almost 15 days late and then really heavy and then fluctuate between non existant and that. The gynecologist said it was normal but its doing it worse. I took a pregnancy test after 17 days because there was no symptoms of my cycle or anything. I have a white substance that leaks quite frequent. No smell, i havent had sex in 6 months and my body is just doing something random. Its been 18 days no period but my breasts are very sore. WDID?
