6w5d and oh so tired

Wow i never knew I could be this tired. I just didnt know that it exsited being this tired. All I can think about is sleeping. I woke up this morning thinking about going back to sleep. I dont know if Im going to make it all day at work or not. I may go home at 3 because i cant keep my eyes open. It doesnt matter how much sleep I get. I keep telling myself that its a good thing. It means there is a baby taking all my energy. I cant wait till friday when I get to see the babyies heart beet for the first time. I just kno wthat seeingit will put so manyof my fears at rest. I keep thinking it may be a blighted ovum but i know its not. God is greater than my fears and this pregnancy is goingto be great. I just want to see the little heart beat so so bad. I am lucky so far no morning sickness just this never ending tiredness. I had my first experiance with growing paind yesterday. It was crazy. It hurt so bad. The doctor saud my uterouse looks goo dand is big like it should be and my beta numbers are great. SO I have alot to keep me positive. But that thought is always there. Once i get to hearthe baby i will feel so much more better.
