Weird AF

AF was right on time. Cramping was pretty bad (normal for me) and a LOT of breast tenderness. CD1 was heavy, CD2 was medium-ish, CD3 was light enough I didn't even wear a tampon or a pad to bed. This morning, it was a milky pink and there wasn't a lot. My period normally lasts 5-6 days. I've also had random nausea for about 2 weeks with bad gagging every time I brush my teeth. ?
