For the past two months my periods have been very light, usually they are medium to heavy. I think I may be pregnant but I don't want to get to jump to any conclusions. My breast have been sore, I've been tired, irritated, using the restroom more times in a day that I can count, along with other symptoms. At first I didn't think anything until one of my friends notice the changes with my face, I thought I was just going through an ugly period, my skin is clear of acne and bumps, which is a first, but I have blotches all over. I took a home pregnancy test, it was negative, but I'm still going through these changes. Could I be pregnant?
