My body is out of whack! Is this ok?

I've been on birth control for about 4 months. My boyfriend and I aren't TTC however whatever happens happens. So my period was due to start the 10th, started two days late nbd, however it stopped after only two days. Come to think I didn't have any symptoms of my period coming like usual (tender breasts. And cramps), however I was still moody as hell the week leading up. What I noticed the other night was that my areoles have gotten much bigger, bigger than they've ever been in my 27 years of life. And I've had a BFN about a week and a half ago.
