First cycle of clomid and I’m beyond confused

Alright can someone explain these instructions to me ! This was my first time seeing this gyn and she prescribed me these meds after 6 months of ttc but was no help in answering my questions!!!

Okay week 4 do I take the progesterone with the metformin or do I stop the metformin?

Why did she put take a pregnancy test in 4-5 weeks is that from today or is that before I take the clomid ?

Are there any side affects to these meds ? When is the best time to take them ?

Can I still drink pink stork ?
