Excuses!!! Hiding pregnancy

B💑👪

Soooo.. My dr appt was just bumped up a few days. Originally, my appt was for Saturday so my husband was going to stay with our 2 year old while I went to my appt... well.. things have changed. They called to reschedule for Thursday! That means I need to find someone to watch her.. which isnt normally an issue except we havent told anyone I am pregnant! I definitely dont feel confortable telling anyone especially not my MIL who is the person that watches her when we need a babysitter. To tell her is to tell the whole world cause she cant keep anything to herself!!! I need ideas and excuses. My husband told me to say I am going to the dentist but I literally just went 2 or 3 weeks ago and she watched the baby for me.. I dont want to ask my mom to watch her cause same reason! Helpppp!!! Anyone in the same situation? What do you say?
