Ok so my periods are ALWAYS very regular. The only time I've ever been more than 4 days late I was pregnant or on bc. I haven't been on bc for almost two years. I've taken 4 tests in the past week and they've all been negative w/ no faint lines. Thing is I feel pregnant..lower back pain, discharge, tender breasts, headaches etc. I had an abortion in June (no shaming pls) with regular periods since and was wondering if the abortion could be connected to this issue or if anyone's experienced kind of the same thing and had advice.
