My period was due on 15th August 2018 I done 3 tests which came back negative. My periods are never late and always have a 27-28 day cycle. I've all the pregnancy symptoms. I started bleeding on 2nd September which was very heavy and have never experienced anything like this in the past. I'm having lower back pain and pain in my legs and heartburn. Could I be pregnant as I'm still bleeding but less than before. I went to A&E yesterday and they only done a pregnancy test which came back negative and sent me home saying I should try and do another test at home in a few days. I'm confused me and my husband have been trying for a baby for 2 years.
