Woke up in blood😔

Paige • 23- UK. Our little pea due November2017 ❤🌈🌞
This week has went from amazing to awful and all in the space of 24hhrs. I just keep thinking why us? Why me? What did I do wrong? 😔😔 I got my BFP on Monday faint lines on 3 tests and confirmed 1-2 weeks by clear blue. Rang doctors for them to confirm and received a negative urine sample. Tested clear blue yesterday which said not pregnant. My emotions are out of control and this morning iv woke up to bloody knickers which seem to be getting worse. I don't know what steps to take next shall I just let it past & take care of myself at home or seek medical advice from a doctor? I don't really feel comfortable going to my doctors in general never mind with everything that's happened. I was 4 weeks 4 days. I don't know what to do, what to do next or where to turn too😔😔😔 Any advice ?
