Y'all, I feel like I'm having to completely relearn how to period. I got my first one at 13 and aside from changes when starting new BC or major life events have always been completely regular (every 28 days, no spotting, starting heavy with the first day being the worst for cramps then declining over 5 days or so) Over the past year, I started getting breast tenderness around ovulation which never used to happen but I know is normal for most women. Then, within the past few months I started spotting like three days before my period and this month the spotting started like nine days beforehand. Not at all heavy, just pinkish discharge. I even thought it could possibly be implantation bleeding but Old Reliable came just on schedule. Another unfortunate change is that while I used to only have one day of bad cramps then maybe a bit of lingering pain the second day, in recent months the cramps have lasted the full first three days. I'm nearly 28 so I thought this shit had figured itself out long ago. Any one else experienced such drastic changes to their period well into adulthood?
