There are some herbal products that one could try - I personally don't have any I recommend but I do advise you that if you don't get pregnant within 2-3 months of ttc, see a re (reproductive endocrinologist) to get some advice.
You could also post this question on the fertility forum - there are lots of women over there ttc that are in their 40's and perhaps they'll have some good advice.
It took us years to conceive until a doctor gave us good advice. Have lots of sex at least once every 24 to 48 hours. Start trying when your period starts. You will be pregnant soon.
Go to a fertility specialist to check out your eggs and his sperm if this doesn't work. Give it about 3 months.
