I have same problem as you gals too in the past. But I got preganant after I drank the herbal tea that I found on internet.
Here is the link, please see (二). This doctor, 吉叔, is very famous and expensive. You can copy the prescribtion and try asking your doctor is it suitable for your body.
I used to go to 調理my body cause I also suffered from coldness in the past. Frankly, I spent around 1 year to make things right again. Then I drank this formula and got bingo. My boy is almost 2 months old now.
