Subfertility

ouples with primary infertility have never been able to conceive,while, on the other hand, secondary infertility is difficulty conceiving after already having conceived (and either carried the pregnancy to term or had a miscarriage). Technically, secondary infertility is not present if there has been a change of partners.

Trying to get pregnant?

Pregnancy is not always easy to achieve. Some couples can get pregnant just by thinking about it. While others can try for years and not achieve a pregnancy.

Start timing from the end of the females mentruation. When you take into consideration all the variables, it is a wonder babies are born at all.
