cousins due in the same month (hopefully)

My sister is waiting on her ivf results and i just found out last week i'm having my second baby!! Another week until my sister gets a blood test, fingers crossed it works :) i'm so excited to be an auntie!! And being so close in age, if the ivf worked, they'll be best friends!! Tons of play dates. I'm so excited already even though we don't know if my sister is pregnant yet.... i just really hope it worked this time, i don't know how i'd feel being the only one pregnant when they can't concieve naturally....
