PREGNANT!!!!!

Hey yall this morning I took a test and found out it was positive! I need help with a way to surprise my husband tonight! He is expecting me to have started my period today. We go to a bible study on Wednesdays and usually its us and the couple hosting it (the husband was his best man at our wedding) and sometimes there may be one other person. I already talked to the husband and hes on board with helping with surprising my husband. He doesn't know what the surprise is about yet. I told him I'd call him when I have a plan. I need yalls help with a plan. We have a little girl (16 mo) that we are trying to adopt. She has lived with us for 6 months now. I'm planning to get a big sister shirt on my lunch break but dont know if I should use it. Help!!!
