Hi everyone. Last night there was a strange thing, something like contractions. How I understood it... Pulling pains like premenstrual cramps, every 10–15 minutes my belly would get very hard and an awful pain radiated to my back. All of this lasted about 2–2.5 hours, I endured it and went to sleep. Now my belly hurts a lot, but not inside — it's a superficial pain, i.e. the skin, like from tension. What could this be and what should I do?
