So it was the third time my boyfriend and I ever had sex (couple days after my period) and we didnt know the condom broke and he came inside me so the next day I took plan b and in a week I got my period and it was just like a normal one would be but then a week later I started to get spotting and that lasted for about two weeks and its been about two weeks after that and I'm now feeling nauseous all the time, but no vomiting and i was wondering if that was morning sickness. I've also started to get "menstrual" like cramps and I'm just worried because I don't know when I should be expecting my period since I've had it for almost a full month in september and now it's october so any help or advice would be greatly appreciated!
