So I have been testing and I have got BFN each time. I have had a few symptoms Ive never had before AF, usually I can tell a week before AF is due. My nipples were incredibly painful, it was uncomfortable to wear a tshirt. I have had a weird fluttering feeling at the bottom of my stomach. I have all of a sudden started getting a lot of spots on my chest and stomach and today I have suffered with terrible heartburn eating rennies like they are sweets. Despite the BFN, is there still a chance I could be pregnant??
