I, too, had spotting during my pregnancy and mine happened even during the seventh month. Though, all went fine, I must suggest that whenever there is spotting you must see the doctor. Doctor would be able to guide in the best possible way as each individual's body acts in a different way. For me spotting at seventh month did not cause problems but for someone else it can, so it is best to seek doctor's advice at the earliest.
I guess u r referring to spotting. it's best to consult ur gynae, give a cal as its hard to tel if it's normal or not.
