My last first period is 26th December. I had protected sex on 7th,8th January but i took 1 pill of prostinor 2 immediately because i feel like our condom brokes but i missed the second dose which I suppose to take 12H later. Then i had sex on 25th and our condom slipped and got stucked in my vagina but it was removed immediately and i took again my prostinor 2 immediately and also my second dose after 12H. My period was expected 23rd January but now im 7 days late. Is that because of the prostinor ?
