Is It Normal To Have Prolonged Black Spotting After Taking Primolut N, And Will Tranexa MF Help Stop It?

Hello doctor, Last month I had taken primolut n twice for 7 days as per doctors suggestion to postpone period due to a family function. I had my periods on 8 and it was over by 12 of march. Post that I am spotting which is black discharge. It is light and no seen always on undergarments. This also happened in 2022 july when I had taken primolut n and gradually had stopped after 20 days Or so. I had done an ultrasound and report was normal. Doc had asked me to take pause xt for 3 days twice a day and the course got over today. But still I am spotting. Now doc has asked me to take tranexa mf for 5 days. What to do? Even though there is no physical discomfort but wearing a panty liner for so many days is irritating.
