Ok my heart is pounding as I type this. I went to make the bed back up as I got out of it this morning and there's a wet patch about the size of my palm on the mattress. I've taken a photo of it as evidence!! My bed sheet is white so it looks clear. I have no pains or blood. I've rung my MW and am waiting for a call back. I'm terrified if it is because I'm only 31+3. Baby was crazy active in the early hours of the morning.
