I didn't plan on telling my parents till a little further on. But my mom scheduled for me to get my wisdom teeth out... So I had to tell her why I couldn't go into surgery. They were a little shocked at first. Never really mad. But now at 32 weeks my mom is so excited. She can't stop buying things. So far I've had a very pleasant pregnancy. Lots of water and bath time. :p
If you're anything like me, water, extra strength tylenol, dissolvable Zofran and lots of pillows will be your best friend. Lol. Also, just sit your parents down and tell them. They might be upset at first but they'll be even more upset if you wait to tell them. If you tell them now, it'll show them that you're responsible enough to own up to your mistakes (unless this was planned. Either way, congrats.) Good luck, hun. :)
