I thought i may have been having pregnancy symptoms and then a day before AF was due, I came on! So obviously I was gutted. I came on lighter and shorter than usual and now its over! I feel as if i have butterflies in my stomach and when I'm at the gym I feel very uncomfortable when jumping or bending down! I have had the worst headaches and have been feeling sickly for ages. I had breast tenderness before AF was due and now its gone but I do get the odd twinge in my stomach now! I took a pregnancy test 3 days before AF was due and it was negative...do you rekon its worth taking one again or am i going mad!? My stomach feels tender and harder and seems bigger!! (could be that im just getting fatter) HELP ME SOMEONE PLEASE!!
