First time in clomid and LH is confusing!

Sabs

Hello friends,

Took my first Clomid CD 3- 7 scheduled for a IUI but ultrasound shows follicles only at 5mm on CD 12 today. But my LH has been positive since CD 8 and peak on CD 10?

I’m so confused because I’m not sure if I have ovulated early or clomid is messing with my LH and my follicles need time to mature??? (5mm is super small for CD 12).

Please share your thoughts or experiences as this is my first time planning IUI and taking Clomd. Thanks!!!
