I'm 30 weeks and 4 days pregnant. Is it normal to feel extremely tired and not wanting to get out of bed. I just eat and go back to it. I've been feeling exhausted since yesterday. I'm very active every day. But today I've been feeling weird, my stomach is tight, back hurts, my eyes are literally closing, I go pee every 2 minutes. This is really frustrating. What do you all think it is?
