I am not sure what you could do besides seek medical intervention, but wanted to mention that it is 35 where pregnancy risks increase significantly. Not 30. I am 30 now and due in a month, and my boyfriend is 44. Sooo. there is hope!! I would call around. Lots of reproductive physicians will take payments and try and work with you from what I have heard! Best of luck!
I honestly not very good at knowing how to TTC but I wanted to wish you luck and give you lots of sticky baby dust. I hope you get your little bean soon! :)
