TTC after Mirena

Ness • Baby Girl born in 2021

My husband and I are on our first cycle of TTC for baby #1. I took out my Mirena sept 17th after being on it for 5 years. I got my first AF shortly after that and we’ve both been taking pre pregnancy vitamins, cut out alcohol completely and significantly reduced our caffeine intake. I’m now 9DPO according to Glow. From similar experiences, how long should I expect it to take to get a BFP after having the Mirena ?
