What is happening to me?

Sixteen years ago today...I had fallen back asleep Friday night on the sofa only to wake up just a while later with an awful headache. I decided to get up and grab some medicine and  maybe work on the checkbook. I know, not something someone with a headache would normally do but I have always been a little anal about my checkbook, even before my banking days. I sat at the dining table trying to look at the receipts and numbers, my head was hurting so bad. I had always had headaches growing up and a few years before I got pregnant I started having migraines. This was the worst headache pain ever, worse than any migraine and different. The light wasn't really bothering my eyes and the sound of the TV wasn't bothering me either like normal. It just felt like someone had taken a baseball bat and hit me upside the back of my head. I got up and went outside. It was chilly for the end of October in VA. I went and laid back down on the sofa and nodded off again. Hubby woke me up Saturday morning and I told him about not being able to breathe again and then the headache later. I took some Tylenol and went to bed. I napped on and off all day but I felt terrible. I didn't eat much. I didn't really feel sick to my stomach just icky like nothing seemed good to eat. I still had a mild headache and the breathing was still bothering me but we got through the day just lazing around and went to bed fairly early for a Saturday night. Again, I woke up trying to catch my breath and with really bad 'heartburn'. My head was still hurting so I got some medicine and laid down of the sofa. I had taken Tums but it didn't seem to help, then I realized that the Tylenol had eased my headache and my 'heartburn'. I was starting to get really freaked out. All of this was not normal, I didn't think these breathing issues happened until very late in the pregnancy but the icky feeling, the really bad headaches, and everything together prompted me to call the hospital. I talked to the triage nurse in L&D and told her what was going on. I told her the Tylenol made my 'heartburn' go away and her response was Hmmm. She asked me if I had felt the baby move and I said I really had not paid attention. She told me to drink a big glass of water and relax and try to feel the baby. If I didn't feel the baby move to come right to the ER and if I did, well then it was up to me to come in or wait til Sunday morning. I got off the phone, drank my water and relaxed. There she was, my Bailey girl doing flips just like normal. I thought about it and figured since she seemed to be ok, I would let hubby sleep and call my Dr Sunday morning. I went on back to sleep for the rest of the night.
