My niece is 25 and she had to have that Projesterone shot too since she had her son in Nov instead of Jan, he was a preemie but is ok. He will be 2 this next Nov. and she is due in Jan now again. She is doing great so far just found out she was having a girl. I hope all works out for you....God bless you going through all the potty training and plus whats on your plate. Let me know what happens...Best of Luck to you.
