Is Tri-previfem Birth Control Pill Effective In Avoiding Unwanted Pregnancy?

I am having slight cramps and I am not due for my period for 7 more days. This is my third month of being on tri-previfem birth control. My boyfriend and I have had sex without a condom (he didnt ejaculate in me) but I always take my pills on time and never forget them. Is there a possibility I could be pregnant?

Hello dear
Understand your concern
Yes Tri-previfem birth control pill is very effective in preventing the pregnancy as you took pill on time and do not forget to take.
Its failure rate is only 0.5-1 percent.
No matter you used condom or ejaculated inside or outside the vagina as you are on contraceptive pill and its prevent the ovulation.
So do not worry and there is no chance of pregnancy.
You can clear your doubt by urine pregnancy test if your period will delay by 8-10 days. But It think you will not need of that as your period will com as there is no chance of pregnancy.
Hope this may help you
Best regards
Dr. Sagar
