If I had sex 2days before my periods and still get my periods is there a possibility i could be pregnant
To know your safe days this method requires one to record their menstrual cycle length for a minimum of 12 cycles. The length of the shortest cycle and the longest cycle is used to calculate the fertile window. To estimate the first fertile day, 20 days are subtracted from the shortest cycle length. The last fertile day is calculated by subtracting 10 days from the longest cervical length. For example, if your shortest cycle is 26 days and the longest cycle is 32 days, it means the fertile days would be from day 6 to day 22. That’s a pretty long period to abstain so additional precaution would be needed e.g. barrier methods like the condom.
