Pregnancy Info HOME

Hi, my last period started on 3 July, I have since missed a period and am coming up to my next menstral. I am on the pill and have not missed any. I took a pregnacy test which came up negative, so I assumed that I wasn't pregnant and carried on taking my next cycle of pills. The problem is that since my missed period I have felt sick, my br___ts are very sore, I sometimes get cramps in my stomach, I seem to be going to the toilet all the time and I don't seem to have any energy. Should I wait until my next period is due to see if I miss another one or just do another home pregnancy test now??
