Endometrin help

Mc

I just had my IUI Thursday and I thought the dr said take 2 -100mg endometrin starting tonight...2 pills at the same time. My real prescription hasn’t come through yet so I don’t have any written instructions. Has anyone else taken 2 pills at night rather than one in the morning and one at night? I’m definitely on 2 per day but not clear on timing of the 2 pills.

Thx. 2 days down of my tww!
