Call your OB: You left out the most important thing we need to know, which is your gestational age (how far along). However, this combination of symptoms warrants calling your OB provider. Could a variety of things depending on how far along you are. Again, though as an OB physician, please call your OB provider and left him/her know what is going on. Almost all OB's have an answering service, so call.
