My wife used the rest room, and there was a drop of blood on the seat. Maybe she did not even realize it otherwise it would have been cleaned. It is definitely not mine. I have not asked her though, at there is no possibility of it being any one else’s. She is 3 months pregnant, is it normal to have bled. If she doesn’t know she is pleading should I tell her. When I read online what is happening it said something about pregnancy spotting. What is this spotting and why does it arise? Should I take her to a doctor? Is it serious?
