Call your regular doctor right away and have it examined. Cellulitis, if that is what it is, can cause bacteria to get in your bloodstream and cause a serious infection in you and possibly your baby. This can occur very quickly and get very serious. Request to be seen ASAP and in the meantime apply a topical OTC antibiotic ointment to your wound. My daughter had tiny bug bites that over the course of 2 days rapidly progressed to a serious leg infection requiring hospitalization. God bless you!
