Any ideas help!

Natarsha • Been trying for baby #1 since June 2014 .. I have a blocked right side. IVF started April 2016
Ok I'm 11 days late . (Day 6 late I had a negative blood test) so I not pregnant Unless there is a mericle ... Anyway I'm trying to bring my period on using myths don't want medication... And nothing is working !!! I instead have been having upset stomachs and headaches to the point I need I sleep at work at 3pm ! ... I thought maybe iron ..  Nope everything is normal !!! So I'm guessing I'm sick as I never been this late and maybe my body just doesn't like that I'm 11 days late.. Question is do u know anything to trigger my periods ... Or if it's just a missed month I'm suppose to have my fertile week next week so should I just start ovulation kits and the deed to try again?
