Lightning crotch @ 4 weeks!?!?!

Hi everyone! I got my positive blood test this am. Blood was drawn 3 weeks 4 days and my HCG was 96....is that a good number?

I’m having cramps like my period but every now and then I get this quick BAM! Shooting pain right down my vag... sorry if tmi. But it’s so bad it makes me wince. Super quick!!! I googled of course and they say lightning crotch, but it seems to happen more in late pregnancy, not that often in early early pregnancy 😫

Has this happened to anyone else? Should I be worried!?!
