Uy, anak, this is something you really need to discuss with your OB agad, ha, don't wait pa. A rash combined with a positive pregnancy test needs proper checking so your doctor can make sure everything is okay with you and baby. Kaya please go see your doctor or go to the clinic na, wag nang mag-atubili. Sending you so much support, I know it's scary pero the best thing is to get checked right away. Keep me posted, okay?
