I had sex on Monday (November 21) with a condom but it broke and he finished inside me before we knew that. I took plan b that same day. My period was supposed to come Thursday or Friday as my last period was October 26-30. On Thursday (November 24) I had brown spotting and Friday it turned into red blood and was heavy enough to need a tampon. I'm wondering if this is actually my period. It came at the right time and the colour and clotting makes me think it is, but it's a lot lighter than normal. I've heard plan b can affect your period. So I'm pretty sure it is my period but not 100% sure haha. I'm wondering if anyone else experienced a really light period after plan b? I think I will likely take a pregnancy test for my own peace of mind, but should I wait until the end of this week? Thanks everyone :)
