Chemical pregnancy maybe?

My periods are usually regular. Regular flow, mild cramps. This month is so frustrating. AF was just about 3 days late. The first full day I bled, it hurt so bad. Like razor blades and sharp stabbing pains. Wasn't bleeding real heavy but just in excruciating pain, where even wearing a tampon hurt. Today is day 2 of bleeding and it's heavy, not near the amount of pain but moderate cramps. Could it maybe have been a chemical pregnancy? I never tested positive, obviously, but I've never hurt as bad as yesterday with any period. I just took Tylenol to help control the pain. I have an appointment next month, but I'm just looking for opinions until I get there. 😕
