Can I ask for sticky baby dust prayers?

My youngest DD and SIL have been trying to have a baby for almost 3 years now. She has PCOS and it has made getting pregnant difficult. The first Dr. told her she was to young to worry about. She was 20 yrs at the time. I told her not to listen to that dr and keep looking.  She found another Dr who didn't judge her age and say she was to young. After no results for the past year or so, he sent to her to an amazing Dr. who specializes in infertility. He did several tests and started her on different meds and finally a hormone shot. When ever she has any kind of test, he always calls to personally tell her the results.

Today, she had to have more blood work. Then we went shopping and were at JCPenney trying on clothes when he called. She was in the dressing room and I gave her the phone. She started crying and my heart dropped. Then she came out and told me she was pregnant!!!!!!!!!!!!!!! I started crying as much as she did. Two other sweet women in the dressing room started crying with us. I honestly wanted to drop to my knees and say thank you to God for His blessing.  She then called her DH and he was so excited!!!! I don't think he has stopped smiling since she told him. 

I have prayed and prayed to Jesus for His blessing and if He saw fit to give them a child.  My DD is our rainbow baby.  We have 3 precious babies in Heaven, the last one was a girl.  Parts of my heart went to Heaven with each loss.  I am already head over heals in love with this tiny, precious nugget. Any prayers or good thoughts for a safe pregnancy and delivery are so appreciated!!! My heart would be shattered for her if something happens to this baby.

My two other grandkids adore their auntie and uncle and are super excited. (They were with us today.)  This precious baby is so desperately wanted.  We have told a few friends and family.  I want to post on FB but not yet. That is for my DD to do first.
