The most important thing you should know when trying to conceive is when you are ovulating. Give your mind, body, and soul a rest. Engage yourself in a project, class, volunteer commitment and home restoration task, anything that you're interested in. It is best that you visit a doctor to get more professional tips.
When your ovulating have your husband save up for 2-3 days before then after you do it elevate your hips by putting a few pillows under u and lay there for 15-20 min. It's a long time but it'll work! Good Luck!
