Hate not knowing what's happening?!

Jessica
So I had some bleeding the day after me and my partner had sex and this lasted 2 days, spoke to doctors and he suspects miscarriage but register with midwife so they can send you for a scan, so spoke to midwife and she says she's not sending me for a scan as she doesn't suspect miscarriage. So my question is, who should I believe? I don't believe I'm having a miscarriage but I don't want to think my baby's there when he/she isn't. My hips are hurting which I'm putting down to them expanding, my boobs hurt still, I'm still nauseous, bloated and soooo tired (but think that's emotional drainage). Anybody have same experience or any advice? Xx
