Okay, so not only does my problem affect me, it frustrates my husband to no end and I don't know how to correct it!
I sleep... a lot. I get to bed frequently around 10-11pm and I sleep until like 1-2pm! I am pragnant and I understand fatigue is normal, but this is ridiculous. Ive always slept a lot, but it has gotten worse in the last about 2 years. If I know I have to get up in the morning, permanently for the day with no hope of a nap, I have almost an anxiety attack the night before and I get very depressed because I know how I will be feeling in the morning.
In the evening time, though, I am very extroverted and go-getter. I want to get out and visit people and shop and do normal fun things, but it seems like I only have about 4-6 hours a day to be 'normal' because even after I wake up at 1 or 2, I feel all lethargic and down for a few hours.
I just want to be normal again. I want to get up at 7am and be ready for the day. I want to think of 9am as seriously sleeping in, not getting up way early! Ive tried going to bed early, like 8pm. I still am set to sleep until mid afternoon. And if my husband is offshore and I have no 'reason' to get up, I can sleep until 4pm.
This is crazy. Any ideas on what's going on would be greatly appreciated.

Certainly it could be a medical condition.
You could be hypo thyroid,there are numerous conditions where lethargy is a symptom.
It could also be depression or stress.
It would be foolhardy to attempt a diagnosis via this medium but I do think it should be discussed with your doctor.
It could be something as simple as needing a little more B12 in your diet.
Be sure to take your prenatal vitamins.
Talk to a doctor.

I don't feel depressed... but I don't think Ive ever had my thyroid checked out

You don't always have to feel depressed to be diagnosed as depressed. One of the symptoms of depression is sleeping a lot.

It's okay to sleep now... that baby will keep you very occupied once it arrives.

Well I already have one, but she's a gooooood baby. Lol Thank God! I get up to feed her and play for 20 min or so and she's ready for a nap or loves being in her swing

No wonder you are tired ,with a baby and another on the way! That is exhausting.
You should mention this to your OB at your next visit,you could be a little low in iron.
