Do you believe birth control helped with IUI?

My doctor wants to put me in birth control for a week or two to hold me over so i can still have my <a href="https://glowing.com/glow-fertility-program">IUI</a> this cycle, and not have to wait until next cycle. Or should i just wait? Anyone ever had birth control and it helped get them pregnant ONCE THEY GOT OFF BIRTH CONTROL, or do you feel birth control messed your cycle up.
