Utrogestan 100mg

Hi ladies

Have anyone started utrogestan 100mg on 1dpo for 30 days?

I went for trigger shot on monday(day 16) and got a prescription for utrogestan starting today(day 19),but for the whole month...

I am just confussed as to way the whole month,because everywhere i read it says for 14 days.

Doctor did not talk to me about it,when i was about to leave the sister just came running after me giving me the prescription.

Sorry for long post.
