Concerned about how light my periods are, and the amount of days they last, current one started on Friday and today seems to have more or less stopped. About to turn 42, so thinking this may have something to do with it. Usually for a few days prior I get backache and some dull cramps. Concerned this may have a impact on having another baby. Already have a son, conception was natural, prior 3 mmcs and two IVF rounds, which didn't result in a pregnancy.
