Maybe some advice please...

Hello all :)! It’s taken me awhile to get the nerve to type for some help. I am 38 and really want to conceive. I have my period to the day every month and just had my yearly check up and was told that I do ovulate. My period however lasts about 3, maybe 4 days. Does anyone have any advice on something natural/over the counter that I can take to maybe help me out?! Thanks ahead for any possible help or advice :)!
