I think I might be PG with my #4 but I wont find out until the weekend. I have many symptoms and cos is not my first time it really feels that I am. Im now in the horrible week waiting for AF to arrive. I was wondering if the taste like metal in my mouth is produce by the intake of folic acid or just comes to u when u r PG. Every time I was PG I had the awful taste all day long but I used the folic acid every time so I dont know.
