Just need to know if anyone is feeling the same

I know I post a lot on here but I’m from UK and we’re sort of left to our own devices until 8 ish weeks. I’m 5 weeks and 4 days today, my nausea has subsided but my breasts seem to be getting more painful each day, I have occasional cramps in the middle of my womb, my appetite is ok. But why am I so worried something bad is going to happen? This exact time last year I had a D&C because I lost my baby at 12 weeks missed miscarriage :( I’m so scared this is going to happen again or worse ectopic. I just need some friendly gals who feel the same as me, I’m an anxious mess!
