Hello and welcome,
I understand the issue.
If the pills are used as per instructions, irrespective of periods, active pills for 21 days and 7 days off pills or placebo pills irrespective of the period, chances of pregnancy
are very low an failure twice in the same woman is extremely rare.
The commonest mistake with pills are that women tend to begin them on day 3 or day 5 of period every time and not follow the schedule.
If you have been using them as per instructions, then there is no chance of pregnancy.
So the use of condom is inconsequential, meaning that use or no use will not have much effect in relation to pregnancy. However it does protect against sexually transmitted disease
so its use is always wise.
Do not worry. If the pills have been taken properly, there is no chance of pregnancy.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
