..

It's probably a period. Implantation bleeding is very rare, and EVERYONE seems to think they have it.

If you are trying to get pregnant, you should see your OB/Gyn to make sure everything is on track and that you are healthy. You should also be taking folic acid daily, even before being pregnant.

Are you tracking your ovulation using your Basal Body Temperature? Have you done this enough to know when to have sex BEFORE you ovulate?

It takes a YEAR on average for a couple to get pregnant. You should not expect to become pregnant right away after you start trying.
