Please please someone help me is it herpes or not.

hi everyone can you please help me determine what this is. so on the 27th of April I have my period then on the 15th of May I shaved my anus and I used her removal cream Put in mind that the razor I had used was an already used one I know stupid of me . Then two days later me and my husband had anal sex Another two days later we had anal sex againBut this time it was extremely painful it felt like I had a tear. Pooping was very painful but the pain was getting worse and by the 23rd of May I thought pooping was very painful but the pain was getting worse and Felt like they were bumps. they were painful to touch wipe and wash but they were not itchy it was even painful to sit I then had a look in the mirror and I saw one look like herpes according to what I saw on Google. They look like blisters with a white head some of them look like sores that had already opened and they were oozing. it was even painful to cough or sneeze. There was some discharge coming from my anus to. I then called the doctors and was seen on the 28th of May but the doctor said that it looks like contact Dermatitist. She gave me some antibiotics to put on the spots however it was burning me like crazy and the rash the spots have been spreading to my V she gave me some antibiotics to put on the spots however it was burning me like crazy and the rash the spots have been spreading to my Vulva and vagina. so I stopped putting on the topical antibiotic cream and I’ve called the doctors again and they gave me oral antibiotics which I have been taking now since yesterday . I’m still not sure if it is contact dermatitis I’ve been paranoid and looking at Google pictures all day me and my husband are faithful and I’m very scared and in a lot of pain please help me

just to add i didnt have any swollen lymph nodes no fever whatsoever. only headaches from the lack of sleep which was due to the pain i couldnt sleep. its been a week now the pain has calmed down i can atleast sit now. pooping still hurts but not as bad before. im hoping the oral antiobiotic is helping. do antiobiotics help with herpes? if u have read so far thank u any help advice experience helps. ive been married for 4 years we are faithful. and have two kids i was tested for std during pregnancy all came clear but not for herpes so i dont know…

anyone?
