Me and oh decided to start ttc after our wedding in june. I came off my pill 18th June. Had tiny spotting about 3-4 weeks later (no pad needed) and then yeaterday more spotting, today i have what seems to be an actual period. I am wanted to track ovulation, but how will i know my cycle length? Or will i not till being off the pill for a couple months? I will add i was on microgynem for about 6-7 years then on cerazette for 6, so i can not rememember how a period is, let alone anything else. Thanks.
