I am on loestrin 28 have been for 4-5mths now, i had breakthrough bleeding the first 2-3 mths last month i think i didnt but now i am bleeding a week beforemy period is due on the pills . I dunno if i should wait it out more or what. i was on tri-nessa for a month had massive headaches and crazy mood swings so switched to this but the random bleeding sucks and this feels like a period with the cramps and all right now.
