Pre period spotting

Maddie
I've recently had to stop working out as intensely as I used to and my body has definitely noticed. My PMS isn't even the same! I used to have basically no PMS pains or pre period spotting and now I get back pain, cramps, pre period spotting, and acne AFTER my period ends. (Don't sorry I'm not pregnant. I'm on birth control and I never miss a pill). Does anyone else get spotting before their periods?
