Thank you for your query.
At 44, please consult an IVF specialist.
You need to have your ovarian reserve
( capacity of ovaries to produce mature eggs ) tested.
Also, you need to have assessment of the one fallopian tube
that should be intact for conception.
Your husband's semen analysis
also should be done.
Trying naturally at 44 with only one tube is not going to be very productive.
You might strongly consider possibility of ART ( artificial reproductive technologies ) to aid you.
