Okay...curiousity killed the cat. I am 27, two previous pregnancies. I have been trying to conceive for a month now. Normal period last month (Feb. 17) and I am having some extreme sensitivity in the nipple area. EXTREME is a good word. It hurts for the shower water to hit them, cold weather makes them hurt (tingle) and ofcourse touch does also. I've been slightly moody but could be PMS. Pregnancy test is negative (HPT). Is it likely that I am and it just isn't showing up yet??
