Baby Two update

My 12 week check up was a few weeks ago and everything sounded good. I got to hear the heartbeat and I was measuring right on. The heartbeat was 156. Which is WAY slower than McCalls was at 12 weeks. I think hers was in the 70's or 80's? This pregnancy has been so different from the beginning though. I didn't even know I was pregnant until I was probably a month and a couple weeks along. And I was pretty sick from about week 6- week 10 or 11. I don't feel sick anymore, I just have quite a few headaches, back aches and I am constantly waking up throughout the night (hopefully not a sign that I will be getting up all night with this baby?). I don't think I have had a good nights rest for months now. I only had problmes sleeping through the night when I was pregnant with McCall at the very end like the last couple months. But I am definately very grateful to be pregnant and to be able to bring a new member into out family. We get to find out what we are having the end of October or the beginning of November. We are thinking it is a boy.
