THat all depends on when in your cycle you ovulate. You need to pinpoint ovulation in order to know when your fertile window is. You can base it just on having 33 days cycles as you may ovulate earlier or later than other women.
I have a 33 day cycle as well and I counted back 14 days from when my period was due. and had sex a bunch around that time. and now I'm 4 weeks 3 days. good luck! just remember you ovulate towards the end of the month. I found that out after going to the doctor
Thanx ladies!! Great advice!! I have sent you al friend invites, hope you respond!! Thanx for the encouragement as well.
