It sounds to me like you are VERY stressed about becoming pregnant. If you do get pregnant, you wont feel any movement in your belly until ATLEAST 3 months pregnant. The baby is just far too small before that. Most cases you won't feel movement until 4-6 months. anything before that is just a fluttering. 7 months is not an incredibly long time to be trying to conceive. It takes most healthy couples at least a year to conceive naturally. It also depends on what kind, if any, of birth control you were on before trying to conceive. For example, if you were on the depo shot before trying to conceive, they tell you it can take up to 18 months to conceive, before you need to become concerned. The doctor is right that you should not have sex every day, as waiting for every other day gives the sperm a chance to build up enough to make a difference. If you do it too often, it depletes the sperm amounts, and makes intercourse less effective for purposes of conceiving. How are you timing ovulation? Are you using basal body temping(
Ovulation Calendar and Ovulation Chart - FertilityFriend.com) and ovulation predictor kits? if not these will help you better pinpoint time of ovulation. I want to add that even if you are doing everything perfectly by the book, conception can still be evasive for you, if only for the reason that you are stressing. Stress can be a huge piece of not being able to conceive. So try to relax, try to just let things flow. so many women try for years to conceive and the moment they stop trying, they fall pregnant. Its worth a try.
