I did artificial insemination at home on March 21, 2007. I also ovulated that same day( I know cause I can feel myself ovulate!). About a week later, I noticed my breasts were VERY swollen. A few days later I noticed dark blue veins running through my chest that were not there before. I have always been a 38 D and I measured myself yesterday and I measured a 40! About 2-3 days ago I started being sick to my stomach every now and then (no vomitting- sensitive gag reflex). I also started having heartburn (had to look that up cause I have never had heartburn before). I am 40 years old. I am due to start menstration on the 5th of April. I have had NO signs of PMS. I have been on medication (I stopped that the day I inseminated) for PMDS. I usually am overly emotional without my medication about 2 weeks before I start. The only emotion I have experienced in happiness! Could this be pregnancy?
