Hi doctor I just started using trigestrel, 2month ago I was on the 2 month injection and stopped cause it made my cycle complicated, I experience swollen breasts and moodiness and other things so I decided to change to the pill. I tested for pregnancy and it was negative, went on my periods a week ago and this morning began on the pill, started spotting heavily and had some blood clots, I would like to knw is it normal and if I should continue with rhe pill
