How to entice boyfriend

Me and my SO have spoken about TTC but we haven’t been that active about it. We’ve both been full of colds and today I had EWDC. I literally want to pounce on him when he walks in but I know he’s going to be poorly so will be dismissive.

Any thoughts on how to persuade him?

PS. I’m too embarrassed to dress in lingerie in case I’m rejected.....
