Severe itch and rashes during third trimester

omg me!!!! it started from the belly, now its spreading to my chest area, arms and back. contemplating to see a doc because if they were to just prescribe me with over the counter creams its just a waste of money. so im just waiting for my next appt on the 10th. wanted to cry sometimes at the severity of the itch. and it usually appears randomly but more often at night. hang in there mummy!
