What's happening?

Do I look any bigger ?? I was 8 weeks pregnant from 22nd February. On Easter Sunday I got told I had a missed miscarriage all they did was take a pregnancy test and it came back negative. Anyway a month later got another positive test. Started bleeding went to the doctors. They took pregnancy test and they came back negative. They did a physical and said my cervix was closed so I wasnt actually pregnant but didn't want to do a scan. Now I've realised I've been gaining weight, have stretching pain in my lower stomach and twinges on the side also I've had diarrhea . Do you think I look any bigger?? I don't know what going on.
