Good morning, for the past 3 weeks I have been suffering from sore breasts, headaches and lack of sleep, I had my period as normal last month and about a week after the pain in my breasts started. 4 days ago I had intercoarse and afterwards found spots of blood which has never happened to me before, my husband and I are trying to conceive and he went through a vasectomy reversal last year in September. I did do a pregnancy test a day after I found the blood but it was negative so I m a bit worried as to what may be wrong with me.?
