Am I getting ahead of myself

Am I going to far and getting ahead of myself? It's really early days but Iv wanted this for so long and I'm worried I'm going to build up all this hope and excitement for it to all go wrong and end up having a misscariage! I spoke to a few of my friends and one of them is a midwife, she said that misscariage does happen normally within the first trimester but most women go on to have full term pregnancies. I just want to be 12 weeks already so I know all is ok so I can do all this stuff without feeling silly! I can't even get a doctors appointment for another 4 weeks and I just feel like there is so much I want to know so I can minimise the risk of misscariage. Does anyone else feel like this? Iv been having cramps quite abit for over a week now and I worry that it's the lead up to misscariage, Iv had no bleeding so I am trying to convince myself that it's just the baby settling in! I'm so sorry this post is so long and me just rambling on, I just don't know who else to talk to about it because no one seems interested until I get past the first trimester
