I have the same problem so I went to a fertility doctor and this is what he told me to do. Get a calendar. MOST women will ovulate 14 days from the day you start. Im not in the most catagory. He also told me to take my temp every morning first thing. Even before you use the restroom. Write the temp down. When you see a increase in temp that is when you ovulate. It will spike up a degree or two then drop down again. If you are one of the "Most" in women he told me to have intercourse the day before im suppost to ovulate and the day of and the day after. Put a pillow under your hips (this is in the case you have a tilted uterus.) Eating Yams will help too. Oh and drink robitusin (like a teaspoon) everyday around the time you ovulate. It thickens your mucus wall helping the sperm stay inside and get to where they need to go. :) Good luck!
