Trying to conceive any advice?

Yes. Focus sex around the 14th day of your period starting from the first day of a period. Don't worry about it. The more you want to conceive, the harder it is. Just enjoy the sex.
Get checked. If you have been trying to get pregnant by having sex without birth control with ony one partner, you may have fertility problems, you should both see your doctor to get checked out. Thyey usually start by checking the male partner's sperm first, then other testing on the woman.
