Retin-A Micro?

I'm using Retin-A Micro on my face for mild-moderate adult acne.
Within just a few days of starting it I'm getting little whiteheads
(and some red marks that have yet to decide if they are going to
become whiteheads). I've heard that Retin-A Micro can make things
worse before better, but is it true that the "worse before better"
part can happen so early in treatment?

Is this effect any indication that the product will eventually work
well? I'm reading that some people are still in this phase 2-3 month
into treatment! Thats crazy! I cant imagine walking around like this
for 3 months! At least when I was using an OTC benzoil peroxide I got
some dryness and my shirt collars turned orange but it kept me
*somewhat* clear and I never had this type of reaction!
