so confused

so basically last weekend on saturday i started bleeding it was like my usual period ( at 4 weeks 5days pregnant) so my first thought was panic then a lot of people have told me stories about they had that, the hospital told me i was having a miscarriage but i'm still hearing stories that this happened to other people and there still pregnant and doing fine i don't know what to think because i'm still having symptoms and getting even more symptoms in now bloated and my back is aching so much im just confused first time mum!❤️ but a mummy to 4 angels👼🏼
