Pretty sure it's over

Hazel
Last week I was so happy to announce on here that I'd finally gotten a BFP. Four years of trying, 1 previous miscarriage and three rounds of Clomid. I was so happy. For a week I was so very happy. 
Yesterday I got some light spotting and in the early hour of this morning I woke up to very heavy bleeding. 
I knew that going to A&E would be useless as they didn't do anything last time except make me feel like a fool. 
I've been to my GP and they've sent a referral to the early pregnancy unit who will call me in a day to give me a date to come in. But I know that won't scan me, too early. I'm only 5 weeks. They'll give me a blood test and then bring me back for another in a couple of days. I know it's over. I don't need to be told. There no way after this long of heavy bleeding anything could survive. 
It's not fair. It was my turn. I did things in the right order. We bought a house, we waited till we were married to try and start a family. 
We have good jobs, we're good people. Why can't we have a baby too?
I'm heartbroken
