Pregnancy Jealousy

So my SIL and myself both had our first babies in 2021. They were born three weeks apart and we shared the pregnancy journey. My husband and I have been TTC for three months with no luck. I know this isn’t long! Today my SIL announced that she’s pregnant again. It had always been a joke that we would accidentally do it again and have our second babies close together although we had never actually planned any of it. Anyways, I am okay with it but it just feels a bit like I’m supposed to be on the journey as well. Like we should be doing it together. I know it will happen when the time is right but how do you handle these types of situations when you’re TTC and have been unsuccessful 😕
