Do a sexually active woman need to worry about less bleeding during the period?

Hello doctor,

I am unmarried and I had my period two months ago, and after 10 days of my periods I had sex but the condom got torn in a bad way and it was ejaculated inside so I took an oral contraceptive pill within an hour or two. I consulted one doctor and he suggested that I take the tablet Regestrone (Endometrin) 5 milligrams for three days. Also after a few days, I had protected sex three to four times. Last month I had very little bleeding on the first day of my period and it continued throughout the period. The ratio was, a day's bleeding during a normal period was greater than four days of bleeding. I was having pain in my lower back, in the abdomen, and also in the lower abdomen at that time. After that, I did not have a period. A few days after my period I did a urine pregnancy test and it came negative. Do I need to worry?

Thank you.

Hello doctor,

Thank you for the reply.

My concern is that the bleeding during the first three days was very less, so I am a bit worried. I can say it was a kind of scanty period. Do I need to do a pregnancy test again?

Thank you.
