By staying worried you are not gaining anything, I can imagine your stress but as there is no Nadi dosha in your horoscope I’m fully convinced that santan sukha is very much in your horoscopes. Some times we have to get things but get it the hard way. It is like some person who has to walk a lot before he reaches his destination. Once you reach the destination the hard work and efforts dont matter. I see this for you.
Try the natural way, as suggested during the period of Full Moon, read some articles on the internet for easy ways to conceive. It is said that you should remain still and raise your legs after intercourse, you will find many references to those on the internet. Have faith in God and all shall be fine. And remember the more you relax and stay happy the more chances of you to have a baby soon.
