Me & my fiancé had sex 2-3 days before my period and my period came as normal and lasted the 7 days. But since it finished 9 days ago I have been extremely moody, having backache, tired, brown discharge a few days after period when i wiped and felt sick all day yesterday. I have 2 boys already but can't remember how I felt last time. I am not on pill as we have been trying. I think it's too soon to take a hpt but I have a party at the weekend and would like to no whether I will be ok to have a drink if there is a possibility I will not. Plz help x
