Okay ladies I’m on tri-sprintic I have been on this pill previously then switched to the nuvaring before a 3 month break now I’m back in this pill along with sprinactalone, my period is coming without even taking the withdrawal pill, given I am sometimes forgetful about taking my pill but this is my third month on them and in the beginning I took them religiously and still had the same problem if anyone has had this happen to them could you please tell me what it’s from also my periods are super long
