So my last period was April 29 and I haven't had it. My wife and I did a home inseminaton on May 9,10,13,&14 and the following week. I have been very bloated, nauseous, sore and swollen boobs, certain foods and smell bother me that has never bothered me before, missed period obviously, and my cervix is high, soft and closed, headaches, and constantly going pee seems to be every 5 minutes. I have taken multiple pregnancy tests and they all have come over negative. Could there be a probability of me being pregnant?
