Namaste,
Yes you are born with Gemini Lagna and Moon sign too and on verge of entering into Sani Dasa which would go on till 2045.Based on your Rashi chart,Navamsa,Saptamsa chart and Kshetra Sphuta and Deha method,I am humbly of following opinion.
1.Yes there is a Karmic delay in birth of Child but not denial.
2.Some medical issues need correction besides spiritual remedies.
3.The chart of Husband also has a role to play before conclusion, and so birth details of Husband is required.
4.Saturn dasa is going to start.Saturn has chesta bala aspects Jupiter the natural putra karaka, but as you rightly said it is conjunct with Ketu creating anxiety as sharpit Yoga.But Jupiter in Rashi,Navamsa and Saptamsha chart helps. So cheer up.
Please do share your Husbands birth details, and we go to the next step.
God bless
Ray
