12 weeks and more spotting

It is amazing how much my bump had grown. We had our screening yesterday for down syndrom, they said everything looks good and we'll know the results soon. We got to see the baby and he/she was jumping all over and kicking and punching. It was so awesome to see. We heard the heartbeat again at 153 beats per minute. The tech also said the placenta is behind the baby and I read online that will make you show sooner and bigger, makes sense. 

The baby had his/her arms up and was waving at us, so cute. But had the legs crossed so we weren't even able to get a guess if it's a boy or a girl. Hopefully were able to see at 20 weeks!

Yesterday evening I went to the bathroom and there was more spotting, this is the 3rd time this pregnancy. It's very light, but any amount of bleeding is so terrifying. The nurse said to keep monitoring it, and it's getting lighter since I was sleeping. The plan now is to just take it easy and rest a lot. My mom thinks it's when my period would be due, it happened at 4 weeks, 6 weeks, and now 12 weeks, so there really isn't a pattern. We'll see if I spot again down the road or not. I just wish I knew why this was happening. I feel like I am doing something to cause this but I have been so cautious. This just takes a lot out of me emotionally and mentally. I am exhausted so watching tv all day sounds nice. I feel like that's all I can do is lay down all day. If it helps or not at least I know I'm trying to make this stop. I am always terrified when I go to the bathroom I will see blood, and eventually I convince myself I'm being paranoid and then there it is. Were just praying everything is ok, it seems so crazy that we just saw the baby and it was perfect and then later I started bleeding. And it was an ultrasound on my stomach so nothing was inserted. Just hold tight baby and keeping moving around and having fun in there! I love you so much and am trying to protect you.
