I'm only 5+5 weeks pregnant, but been getting abdominal cramps for a few weeks. Last night was something else though. I woke up with a searing/stabbing pain in my right side, and really severe, painful cramps right in the middle of my stomach. It took a few hours for it to ease off a bit.
Woken up exhausted and still in mild/moderate pain, so I've phoned in sick. Feel like a bit of a failiure tbh!
