Should I increase from Retin-A 0.025% to 0.05% for acne?

I began Retin-A treatment for acne three weeks ago. Week 1 I used it every other night with no visible progress but also no side effects. Week 2 + 3 I used it every night and have had some mild dryness and irritation, but my acne is worse. Even areas that didn't used to break out are getting acne. Is this normal - Should I just wait it out? How long until I should consider increasing my dose?
