Just got out the hospital

Starting off with that in currently 10 weeks. I been having horrible pain for the last two weeks doctors keep saying everything is fine but I checked the results on 4/9 my hcg level were 86,640 today 4/21 they were lower at 69,876 is that normal or should I be worried? My last pregnancy ended in a miscarriage at 10 weeks so I’m filling my head with ideas I don’t want. Help!
