To really get pregnant, you have to loook at alot of aspect.
1 of them is the temperature.
To avoid getting pregnant...play safe, use condom
If you choose not to use then 3 days after period is the safest according to source from internet and forums
And if you still wanna avoid getting pregnant, yes you can, during period time.
Younger gurls no doubt they can get pregnant easier, if not y ppl wanna married early and y ppl say wen ur getting older about 32 your hard to get pregnant d..i din say cannot but chances is abit low..just like celebrities...is 1 of the best example.
