Hi there. Women can have bleeding that resembles a period (but is not actually the lining shedding as with a normal period). Definitely they can. good luck
it is proven that some women do have a minor periods during pregnancy,not to be confused with spotting. But there could be a light period for a certain amount of time as if it were going with your normal cycle, but I don't think you would be pregnant if you had a very heavy period.
