I had a tubal ligation in "04 and in march I took one dose of depro prevera shot to help with cysts, and since then I haven't had a real period and I have been spotting at least every other day if not every day. I have gained weight about 10-15 pounds but only in my belly, and last night while in the shower I noticed milk seeping out of my boobs, should I be worried about being pregnant?
