My husband and I been trying to get pregnant for about 3 months now. My period is do today but here's the thing. We had sex on the days I was suppose to try to get pregnant, but I have been spotting for two days and today just had a brown discharge. I didn't have the normal signs I normally get when its that time to come on my period. I'm super bloated, have a hard time sleeping, headaches and little cramping here and there but nothing. Any advice
