My period came this month but it was really short and not as heavy as usual. Average is 6 days with one heavy day. This was 4 days and no heavy day. It was also unusual to have brown bleeding at the start and end...usually this is just at the end. Anyway I'm very regular and this was a few days early. I've also had my face breaking out more than usual, a consistent stuffy nose, sore breasts, and I nearly threw up after eating some bland wheat cereal this am. I've been very tired as well and had light pricking cramps nearly every day since ovulation. I took a test at 10dpo that was negative. Has anyone had an experience like this or had a light period and was still pregnant?
