Sometimes, after a delivery, the body needs to make some adjustments to return to the normal hormonal
pattern as before, especially if you are lactating. In such a scenario, many experience this sort of continuous prolonged bleeding episodes. Progestogens given for one or two courses should usually suffice to put the system back on track. You should also check for the possibility of another pregnancy
as you are sexually active. Sexual intercourse per se does not usually cause such a problem unless there is some associated cause. Please see your consultant for further help. Wish you good health.
