I really need help!!! Feel like I’m going crazy!!

I am 4 weeks pregnant and I am experiencing mild cramping..I read that is it normal in the beginning but it can also mean I can be experiencing ectopic pregnancy..has anyone ever experienced with cramping feeling or , bloating,or gas like feeling in the beginning of their pregnancy...I really need to validate my concerns??

Also I already did blood work today, so I won’t have the results of my HCG level till tomorrow and my second result till Saturday. I had a miscarriage last year and now my brain would rest till I get some answers.
