question: Hello, I took Advil pm for about 3 years due to insomnia however I notice it affects my period, actually it stops it completely, I observed this on about 4 different occasions. So last year I changed to nytol. Now I have been trying to conceive but don t seem to be ovulating I have ovulation tests for the past 3 months but it always comes out negative even though I see period every month. Could the Advil and nytol have something to do with it? Also at the time I was taking the Advil sometimes overdose and take 3 tablets of 25mg. Could this have affected my fertility and if yes how do I fix it? Thanks for your response in advance.i am really desperate.
