Hello, at me such question... What Use of agents gives 100 % a guarantee... It is possible to give an example combined use.
Thanks.

100 % of a guarantee are not given with any method of contraception. It is possible, certainly to apply a tablet, suppositories, ten condoms simultaneously...
Whether but think sami-is better to learn to define or determine the fetal days (and their only 3 5 in each cycle) and to refrain from affinity at this time? Absolutely harmlessly and free of charge!

And if a cycle not regular? From 24 till 33 days, what then? Thanks
