Okay so between my last period cycle and the one that’s supposed to start today me and my boyfriend have had sex once we didn’t use a condom but I am on the pill. He says he didn’t finish. I’m supposed to start today Bc it’s my third sugar pill and I always start on this pill but it’s 1:30 in the after noon and I haven’t started and I always start over night I know I’m worrying a little too early but can someone please tell me what I should do. Or when I should start worrying. I would also like to mention that my periods on birth control are usually only 3-4 days and my last one was 7-9 days could it be delayed since my last one was longer or is that not a thing on birth control. Please help it will be greatly appreciated thank you !
