Hi , How are you doing ?
From the history you ave given I don't see ant reason for your not getting pregnant.
Just go through the checklist of investigations to see if you have ant hindrances
to your getting pregnant
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
The medicines doctor has given is just health supplements. They don't improve your pregnancy chances. You are 31 yrs & best time for a lady to get pregnant is till 35 yrs, pregnancy has been seen even till 45 yrs. So do go through the needed steps without delay.
Don't worry you should do well , don't lose hope
Hope I have clarified your queries , do write back if any more queries
All the best
Dr.Balakrishnan
