Sil miscarried and I had chemical pregnancy

So I’ve been Ttc #2 for about 2 years now. My SIL managed to conceive her 4th first try. At her 12 week scan there was no heartbeat 💔

A few weeks later I had a chemical pregnancy but never told anyone except husband and mother.

We have been Ttc this month as usual...but I’ve been really apprehensive this month. Obviously I’m desperate for my bfp but it’s so close to their miscarriage that I’m worried to hurt their feelings.

I know it’s probably wishful thinking because it is taking so long for me to conceive again but how do I approach it if I were to get my BFP?!
