Try not to have unprotected sex(https://www.elawoman.com/blog/birth-control/useful-tips-should-follow-after-unprotected-sex). As told by Dr. Geetha HariPriya(https://www.elawoman.com/chennai/doctor/dr-geetha-haripriya) of Prashanth Fertility Research Centre(https://www.elawoman.com/chennai/clinic/prashanth-fertility-research-centre-chetpet) ,Try not to have unprotected sex amid your period - many people surmise that while you are on your period you can't get pregnant... that is thoroughly off-base! So take a shot at the supposition that there is never a "protected time" to have unprotected sex. On the off chance that this happens, you should utilize condoms and the pill for whatever is left of the pill cycle as per the Dr. Samundi Sankari (https://www.elawoman.com/chennai/doctor/dr-s-samundi-sankari)of Srushti Fertility Centre and Womens Hospital(https://www.elawoman.com/chennai/clinic/srushti-fertility-centre-abd-womens-hospital-kotturpuram)
