CHECK YOUR BED FOR BED BUGS
no one else in my family has these bumps including my husband. Only thing I forgot to say in my original post is that i'm 3 months pregnant.
This can be due to papular dermatitis of pregnancy which presents as an extremely itchy rash consisting of red, raised spots that look like insect bites. this rash can erupt at any time during pregnancy and then spots continue to appear until childbirth when they clear rapidly. Apply some calamine lotion on the rash and consult a doctor for steroids prescription if the rash persists.
I hope it helps. Take care and regards.
