Sorry for typing in English since I suck at typing Chinese.

Relaxed is the key and the most important key. I totally understand how frustrated you are right now because I went through that. 

After 3 years trying and no result, we went to tons of exams and turned out everthing was normal but I just could not conceive. Then we started hormone treatment, many times of IUI. The pain from the medicine and the stress from everywhere even I tried to relaxe and be happy. Still my periods came every month. Just right before we started IVF, we decided not to have kids since it's so hard. Then I was so relaxed physically and mentally since I totally gave up. And two months later, I was shocked to find that I am pregnant. Now I am 30weeks. Everything is fine so far.

So just relaxed. Go to see the specialist not just regular OB doctor. If your husband may have some issue, think about IUI. If everything is on the right track, plan some vacation, enjoy the vaction, and put the baby thing behind. I believe you will be pregnant soon.

越放松越容易怀上，这就是为啥有人都奔四眼看怀孕无望去领养了娃后，很快就发现自己怀上了，还生了一个又一个。

所以楼主一定要看开，旅游容易怀孕也是因为心情放松的缘故。
