I am now on CD19 and i am bd'ing every other day as i am unsure when i ovulate. i have used an average calculator and entered my recent cycles in.... which are 25 35 29 38 42. and i come up with of an average of 35 (34.75 to be exact) so i am assuming i would ovulate on the 22nd which is on thursday. does this sound very accurate or would i just be best to keep jumping on OH and hope i get it on OV day. the thing is i dont really want to start charting otherwise i think ill probably cross that line of remaining sain. and i would like to keep the last shred of my sanity. aarrrrggghhhhh so confused.
