Sorry TMI 😩 very itchy!!!

Sorry for the TMI I’m 16 weeks pregnant and my butthole is soooii itchy that’s it’s getting irritated 😣 I did shave a couple of days ago my hairs around my butthole but I always do and it’s never been itchy like this.. is this normal or do I have an infection? 😩 I haven’t even had sex with my husband cause I’m just not in the mood this pregnancy but this itchy ness is annoying!!
