Hi, Lena, you are lucky to have one child. You have had fertility
treatments in the past & know very well that it takes time & patience & nothing in the world can guarantee a pregnancy
. In addition with passing years, even in women with patent tubes fertility declines. So, be patient & compliant with your treatment. Don't take too much stress
as it will also decrease your fertility potential & don't forget to spend quality time with your kid to make yourself relax and optimistic. Wish you best of luck.
