Hello
Let me explain you something about infertility and
follicular study.
You only mentioned the size of follicle 14* 11 on 15th, 17th, 19th and 22nd days ( follicular study for the size for DOMINANT follicle ( which burst or rupture and liberate or release ovum for fertilization) .
Now note down this report .
"The size of follicle should be around 19 to 20 mm on day 14-15 at least to rupture and endometrium thickness must be around 11 mm to CONCEIVE ".
It means in most of cases ovum release on 14-15th day ( count as 1st day of menses first day).
In your case the size of follicle was not up to a standard size required for liberation of ovum.
As you mentioned that you are taking drugs like benforce-M (benfotiamine+metformine ) as this is a combination of drugs used in the treatment for
PCOD ( Poly Cystic
Ovarian Disease) .
Beside you are also taking xpolde , duphastone i.e.
dydrogesterone for infertility .As you are taking
hormonal tablets so this may be the reason of irregular size of follicle ( due to hormonal imbalance ) .
In my opinion first of all get in
ultrasound of both ovaries to rule out PCOD .
If PCOD present ( more chance ) get in complete treatment for regular bleeding ( menses ) and then deal accordingly .
Hope this information will help you.
