Weird

My period was due on the 24th of April. I started spotting on the evening of the 22nd. It lasted for 3 days. The colour was pink, dull red and brown. I felt little cramps, twinges on my right side and subtle back pain.

I took pregnancy tests, and they were all negative. However, my breasts were sore...now they feel full and sensitive, I pee a lot, have leg cramps, smell everything, a weird taste in my mouth and I am a little nauseous every day.

Has anyone ever experienced this?
