I get to go every week and I get to hear it each time and man your right it does get louder. Friday I will be 15 weeks.
I know what you mean...my husband and I were not going to find out but once we started looking at baby stuff to register for, we changed our minds! lol
I have my next ultrasound on the 17th of Sept and I will be 20 weeks!
I just had my checkup last Monday at 15 weeks and also got to hear the heart beat. It's gotten so much louder and stronger since last month...it's all so wonderful and amazing!
I get the anatomy scan next month on Sep 14 at 9:15 a.m. I'll be 19 weeks, and I CAN'T WAIT!!!
