Hiya I've been ttc for a very long time. I've had 2 cycles of Clomifene (Clomid) in 2011 50mg then 100mg. Since July my periods have been coming every 10-13days (this was due to stress from work which has now resolved prior to that my periods were regular). However over the years it has been very erratic! My job invoves shift work and on calls so I know that doesn't help.
