3rd IUI?

Monica
2nd <a href="https://glowing.com/glow-fertility-program">IUI</a> with donor sperm failed. I'm 27 and have no fertility issues...just a lesbian! Deciding if I should try again now or wait a while. Anyone else with no known fertility issues have to try 3 or more times for their BFP? And is there any benefit to doing <a href="https://glowing.com/glow-fertility-program">IUI</a> cycles consecutively rather than spacing them out?
