So I NEVER spot between periods, never. I had my period 2 weeks ago. It lasted 4 days and I thought it stopped. 2 days later, I was bleeding again, enough that I had to wear a pad but not enough to use a tampon. The next day, nothing. Now yesterday, I started spotting on and off and cramping, into today. I’m not due for my period for another 10 days. I know none of you are doctors and I have already made an appointment with my gynecologist but the soonest I can get in to see her is 3 weeks. How common is it to not spot between periods for 17 years and then all of a sudden it happens?
