For the last 3 weeks Iv been thinking I might be pregnant. Ive been very fatigued, moody, and Ive have hard bloating sense my period (feb 13) and it was only 2 days long. I recently lost a large amount of weight (around 41/2-5 weeks ago) I had no appetite and the sight of food made me sick, about few weeks ago I started eating way more than usual, and been having cravings for things like ice cream when Im lactose-intolerant. Ive also been on birthcontrol for 10 months and havent missed a pill. I do have back pain and headaches but I think thats from my car accident back in October. Should I waist the money for a HPT?
