I went off birth control 4 months ago and my husband and I have started trying for a baby in the month of May. In the middle/end of the month I started experiencing some symptoms like leaking breast, tired all the time, peeing a lot, mood swings, hurting during sex and cramps in my lower stomach. I started my period on May 3rd and stopped on May 6th. My husband and I had sex everyday the whole month of May, I took a pregnancy test and it said negative but I have not started my period yet. My period started on April 6th and I had a perfect 28 day cycle and started on May 3rd. I am now 31 days and have not started my period, could it be that my cycle changed? If so why am I experiencing all these symptoms? My body has never acted like this before and I have had one child before so I am familiar with the symptoms that come along with pregnancy.
