Im 5 weeks pregnant up until this point I have only had minor cramping on and off. In the middle of the night last night I was woken up with this sharp stabbing sensation on my lower left side. It was really painful to the point that I had to sit up until it was gone and had to check for bleeding after! It lasted for around 5 mins, there was no bleeding and there's been nothing since. It really frightened me at the time though... has anyone experienced anything similar?
