Confused!

KC

Sorry in advance for the long post. I stopped bc pills in October 2018. I had a 5 day af in Nov followed by a 7 day af in December which is normal for me. I was 13 days late in January! Then had what seemed to be a heavy 3 day af on the 20th and boom it disappeared. Ive take an outrageous amount of pt all negative. Spotting off and on throughout. Now yesterday appeared af had returned heavy but now gone again! Ive been crampy the whole month with lots of other pregnancy symptoms. Anyone had this happen? I need insight before I schedule an appointment.
