I’m so confused (trigger warning)

Kate

So in July I had a miscarriage (I believe). My period was 7 days late and usually regular 28 day cycle and had positive pregnancy tests using a couple different brands. I had severe pain in abdo area that took my breath away and brought tears to my eyes, followed by 3 days of heavy bleeding and then nothing. I’ve since been having periods, although strange ones. They’ve not been completely regular, starting a few days early or late and lasting between 2 and 8 days (I’m usually 6 days) and I’m getting negative tests. Only problem is I FEEL pregnant. I’m constantly exhausted, I have food aversions, cravings, headaches, vivid dreams, weight gain, and random abdo cramping throughout the month. I live in the uk and I’m a bit worried about going to my doctor and being told I’m just being silly or it’s wishful thinking as my daughter is no longer a baby and this would be my 3rd pregnancy loss. Any advice or similar experiences?
