I've been on the pill for 3 years now, and I haven't had any type of bleeding for two months. My last light period was from the 27th-29th May 2013. I'm 31 years old, very small size (6-8), was weighing 39 kgs, but in 2 months, I'm now 43 kgs, my appetite has grown, and so is my stomach. I did a pregnancy test in mid May, turned out negative. But my stomach is suddenly changing (with 2 male friends asking if I was pregnant)! I have had 2 separate random days when I felt nausea, but no vomiting.. :(( Should I be worried?
