From your post it sounds like in your momma gut you're concerned about what is happening... and I think that's your best indicator of what to do. A call to your doctor sounds in order... whether it's something to worry about (and those are some very significant symptoms IMHO) or not, you'll have an answer- and your peace of mind is worth it! My guess is that your doctor will also be very glad you called.
Keep posted when you can-
