What is the absolute earliest you could start seeing signs? My husband and I noticed my nipples and areolas have gotten darker (which I've never noticed before) and they are SUPER sensitive and a little sore. We are TTC and my ovulation week was last week. We had sex but not a lot of it (I know it can only take one time). I'm supposed to start my period late next week. Should I wait and see? Am I over analyzing it? Thanks in advance!!
