Constant worry...

I had a mc last year at 6 weeks. Got my bfp nearly 2 weeks ago.booked in for a scan Friday. Since af was due ive had cramps also tender boobs mood swings and constipation(sorry tmi) all I've done every single day since I found out I'm pregnant is worry!! Every single pain makes me think I'm miscarrying again I feel like I'm going crazy!!! I can't see this pregnancy being a full 9 months all because of what happened last year😢😔 I can't get excited (very hard) im just a constant paranoid worry mess!! Really don't know what to think and feel! This miracle is such a wanted and already loved baby I can't lose this one too!!
