Please tell me this is a ingrown hair

i shaved this past friday! my husband and i were on a break in the relationship he told me he did sleep with one girl but that he always wore a condom (i know condoms dont prevent some things)
well sunday rolls around im sore down there in general red everywhere like ive been rubbed raw sorry tmi but i found this what i thought was an ingrown i messed with it a bit to see if i could see a hair folucule and its just at the hood of my vagina and i cant get a good look. ive called my doctor and my obgyn left emails and voicemails but due to covid they are all still shut down.

looks like an ingrown to me. if you have a small flashlight, try to shine in on the other side in a dark room and see if you can see the hair in it
