I have been really bad this month with taking my pill... i kept missing days and then trying to catch up, then forget again like 2 days later. by the end of my pack i had missed 4 pills. but i stopped as if it was the end of my pack because i was confused wether to go on. I have been experiencing really bad stomach and back pains for nearlt 2 months now and it has been really sore and stabbing like pains. so i dont know if this symptom has affected me to taking a heavy bleed in the middle of my cycle that lasted around 7 days. i thought it was an early period coz thats what it was like, but the blood was very thick and i had alot of blood clots. now a week and a half later my period has come and is the just like my regular period, heavy for a day then getting lighter. i am so confused and dont know if this is regular to happen as iv never experienced it before.

please help?
