Braxton Hicks at 8 weeks ??!!

Hey there

I’m 8w 3days ( 2nd pregnancy ) my pregnancies are difficult I spot and bleed and usually on miscarriage threat ...

anyway now I’m ok not spotting Thank God!!!

But I feel random waves of tightness similar to Braxton Hicks !

Could it even be ?? When ur baby is the size of a jellybean ?

Should I be alarmed ? Is this the beginning of a miscarriage ? Is it possible to feel BH this early !?
