Alright ladies, opinions and advice please!

I woke up this morning not feeling the best. I'm 31 weeks tomorrow. It seemed as if my morning sickness was making a come back. I still have some Zofran from first trimester so I took one, had some ice water, and hoped to feel better. I never did start feeling better, but my son woke up and my day continued, no time to just sit and rest. My SO left for work, gave strict instructions to keep in touch with him, at least a text once an hour to let him know how things were going. I had a placental abruption at 34 weeks with my son and as that time approaches he is becoming very nervous. I haven't had any increase in discharge, but I have been light headed all day and unable to eat. I've also been having random sharp pains across my stomach. They aren't Braxton Hicks, no tightening or anything, just pain. Nothing consistent or constant. I've also had just a bit more pelvic pressure today, but it comes and goes as well. As the day progressed, I've just felt worse and worse. No fever, no chills, no aches, nothing to make me think it may be a virus. What do you ladies think? Just third trimester kicking my butt or something I should be concerned about?
