After 2 miscarriages I am so nervous. Today I am 3w3d (aunt flow due Wednesday) and some of my symptoms come and go. My boobs are sore on and off and itch and I'm tired one minute but ok the next. Last few days I have been a little nauseous but today... nothing. This morning I woke up to a mouth sore which I've never had before (google says its early preg. Symptom; praying it is) took a test this am and it's still positive. Is this normal? Im sooo nervous. Trying my hardest to stay calm.
