I am about 3 weeks late on my period. It was suppose to come December 23/24. I have NEVER been late, the most is by 3 days. I took a home pregnancy test December 31 and January 4th and both negative. Ive had morning sickness, peeing every 30 minutes it seems, heartburn,headaches, nausea, eating differently. I had spotting before I was supose to get my period and had cramps but no period. I am NOW SHOWING. Ive always had a flat tummy and now i got a big bump that everyone notices and i havent gained a pound. Has this happened to anyone else? When did you find out you were?
