Hi- first time writing on here!!

My husband and I had a condom break 2 days ago on the 9th (2 days before my period was supposed to start today on the 11th) and just as a precaution I took plan B within an hour of the accident. I don't think I was ovulating because I have a 27 day cycle, but just wanted to be safe (never taken plan B before and not on birth control)

I read that plan B messes with your cycle and is supposed to thicken your cervical mucus. Today my cervical mucus seems to be way more watery instead of thicker. Is this normal?

Also- has anyone else taken plan b right before there period? When did yours end up starting? Mine still hasn't yet!
