I had protected sex on the 6th of October, took Plan B that night even though there were no breaks I was just worried, I got my period a little late from the 15th-20th. Now I had sex on the 27th, condom didn’t break (it also was a spermicide Trojan condom) and he pulled out like 10 minutes before he finished. My period was supposed to start on the 9th but it’s now the 11th and I haven’t had it. So I was wondering if plan b could have still an effect on my periods being slightly off? Because we were very very careful. (Also I believe this past week I had some sort of infection down there because it was itchy and I didn’t know if that could play a role on this too) please help!!
