AF is supposed to start on the 28th and I've been experiencing mild cramps, lower back pain, clear sticky CM, sometimes bad indigestion, headaches, and today boobs started to hurt. I don't want to take test yet, I'm trying to wait patiently. Just wondering if it's just PMS signs or pregnancy signs? FYI I have been pregnant before but I never really had any symptoms besides mild cramps and missed period. But I lost that one at 3 months. Any advice would be appreciated:)
