This may sound weird but I'm just a tiny bit nervous. I have felt like crap all day today with nausea and heartburn and headaches. Also when I finally got out of bed I noticed a sore spot on my belly. Just one spot right at the top of my bump. This makes me nervous cause my best friend had a placental abruption and the days leading up to it she said she kept feeling pinching and tugging pains inside which we later determined was her feeling the placenta ripping away. Her and baby were thankfully fine even though he was 6 weeks early but I'm only 30 weeks today and I'm scared.
