Could I be pregnant? I know I did the deed during my most fertile days... I know this because of the at home ovulation test kits. Well that was 7 or 8 days ago. The past couple of days I have had shooting pains in my breasts...very noticable and uncomfortable pains. I know it's not all in my head. I have also had some CM for the past week it seems. I have also had bad heartburn. I have had a weird feeling in my stomach...like it's knotted up. I was pregnant a year ago and then had a MC... I remember my symptoms then being a burning sensation in my nipples but that was a day or so before I got a positive pregnancy test. I don't know when to test. Last time I was pregnant I got negatives all the way up until the day my period was due and then a positive. Well...I will keep you updated.
