Should I tell my boss about my FET?

I had my fresh transfer last month which was unfortunately unsuccessful.

I told my boss (who I’m very close to) all the details throughout the whole process.

The day of my transfer she was texting me all throughout the day over work problems and I told her I couldn’t handle anything at the moment as I was getting my transfer done. Mind you, I took that day off and the 2 days after to “relax”.

When I went into the office a week after my negative beta, a few coworkers came over and asked me about my transfer and they said they were sorry it didn’t work.

I asked them how they knew about it and they told me our boss told them.

I was so mad that my boss would tell my business like that. She knew how sensitive this process is. I never told her not to tell anyone but I thought it goes without saying.

Well now that I’m going in for my FET this month, I completely kept quiet about it. She’s asked me if I was going to do another round and all I respond with is “I’m not sure, we are taking it one day at a time”.

I have to take time off for my next transfer and want to not have my phone or laptop with me so I don’t have the added stress.

Idk if I should tell her about it and just say don’t tell anyone. Or should I just keep quiet about it.
