You are running Moon/Venus now? Did you have mental (Anxiety/Depression) and few health issues over the last year or more?
I am not proficient enough to tell you the exact time of child birth. But I guess now it's a good time to conceive provided your husband also has a good fortune for the results to fructify. Keep trying. May god bless you.
If you are a Hindu, try reciting the below sloka continuously. Abstain from non-veg if you are a non vegetarian. But also consult you physician before changing the diet.
Chaturbhih shri-kantaih shiva-yuvatibhih panchabhir api
Prabhinnabhih sambhor navabhir api mula-prakrthibhih;
Chatus-chatvarimsad vasu-dala-kalasra-trivalaya-
Tri-rekhabhih sardham tava sarana-konah parinatah
Thanks
