If you're on HBC, do you still experience symptoms of PMS before your period? I was under the impression that since the hormones override your natural cycle, you wouldn't, but my body is telling me otherwise right now - I feel irritable, bloated, and a little crampy! This is my first month on HBC, and it's right around the time my period would be due in my natural cycle. I'm on Loestrin 24fe, which has 24 active pills, and I have 2 active pills left, if that makes a difference. I haven't felt any side effects during the rest of the month.
