Upper abdominal pain first trimester?

I’m currently roughly about 5 weeks pregnant with my rainbow. My first ended in miscarriage so of course I’m nervous. I’ve been having cramps in my lower abdomen on the right and left side (alternate and not constant) which I didn’t really feel as a threat. However what does scare me is the upper abdominal pain. Is it normal? I’ve been stressing lately and I’m just worried I’m going to lose my rainbow as well.

Please let me know what first trimester pains are normal. I won’t have an appointment with my OB until August 7th /: I just need some reassurance that my baby is ok
