I had ovulated last month around my 14th day, I had really sore breast a few days after. I had sex with a condom on days 14-16. My breast were abnormally sore, and my temperature was constantly high for the next week or longer. I usually get my period on day 30 pretty much exactly. I ended up starting my period 4 days early, and it only lasted for 3 days, compaired to the 5 days its usually here for. It wasn't a heavy period. It ended, but for the five days after that, I would have a pinkish color discharge only when using the restroom. I took pregnancy tests, and they all came back negative. I am now on my 11th day since my so called last period started. I should be ovulating in about 4 days, and I'm having a really bad case of pimples on my back now. Do you know what might be happening?
