Last cycle I started my period on July 1st. I had an LH surge on cycle day 17. This cycle, I started my period on August 2nd. I can only have intercourse on August 16-17. I am wondering if LH surges are the same days every cycle? Cause that would put me at August 18 (cd 17) for LH surge and ovulation on August 19 (cd 18)
