Clomid with periods the last 4 days

[Myoneandonlyds]

Conceived my first child on my first 100mg clomid cycle back in 2014.
Fast forward to late 2021, gp referral to hospital and the fertility nurse prescribe clomid again. (wasn't trying in between)
As I don't hardly ever have periods I was prescribed norethisterone. It takes 5 days after taking the last pill for my bleed to start but then I only bleed for 4 days.
Clomid is supposed to be taken on days 2-6, will this still be effective if I only bleed for 4 days?
Has anyone been through anything similar?

Doesn't matter how long your period is, It just needs to be taken at the beginning of your cycle. Good luck 🤞🏻

I see! Thanks very much for your reply and your good wishes
