Hi ,
That's quite a history. As she has already given birth to a baby, her chances for a second
pregnancy is very high. But her age is a problem. After 40yrs chances of pregnancy reduces drastically. But pregnancy do occur after that too.
I would advise you to have her Serum AMH Level within first 10 days of her periods, to know if she has good number of eggs. If normal no one can assure you a girl baby. but can only assure a baby.
Kindly see if the following checklist of investigations is done
Husband-
Semen analysis at least 2- done 4 weeks apart preferably in an
infertility center ( examination done by andrologist), Blood sugars
Wife - Blood Sugars,
Thyroid profile
Ultrasound scans to evaluate
Uterus , Ovaries & adnexa
Confirm tubal patency- most important- Tube is the connection
between uterus & ovaries( the bridge where sperm meets the egg &
forms a baby) this is size of hair follicle & cannot be seen on scans.
So check with HSG( Xray with dye), or SSG ( Scan with dye) or Laparoscopy
If all this done & found normal , nothing can stop a pregnancy with God's will
There is no specific food which can increase fertility.
Hope I have cleared your query
All the best
Dr.Balakrishnan
