Even though you still get a cycle, it is possible that with each month you are producing less estrogen
. This begins to occur in your late 30's and early 40's.
Here are some options to consider if the problem is persistent:
1. Replens - this is a long-acting vaginal lubricant that helps to "hydrate" the vagina
2. E-string - a vaginal estrogen ring
- a vaginal estrogen tablet
Wait for the results and see what you doctor says. I am sure that you will be able to find the cause and/or long term solution. Good luck!
