Hi all, I need some advice. I am on the contraceptive injection and havnt had periods with it. However last week I started to get spotting, on Sunday morning I woke up with very intese lower abdominal cramps, and very heavy bleeding. On Sunday night I passed what looked like a large sac, sort of greyish and bloody, with more very heavy bleeding and cramps. I just want to know if this is a miscarriage? And if it is what do I do now? I went to a and e on Sunday and he said was a stomach bug, and did no tests on me. Thank you in advance x
