finally ovulating and the mother in law comes

I was so excited for this week!!!!! My phone keeps telling me today is my most fertile day.... but my mother in law just flew in. 😩 why me. I know most people would just do it but our doors are more like pantry doors, you know the shutter kind. You can hear everything since she is staying in the living room and stays awake past 3am omg. Do I really have to wait another month or should  I just push past the embarrassment of her hearing us....
