I have been staying with my parents over the past few days, which was very stressful and I was also sleeping on an uncomfortable camp bed which didn't support my bump at all. Yesterday evening I found a long, vertical, what I can only describe as a 'crease' down my left side. It looked too big for a stretch mark, and it's gone this morning. But I wondered if it was a result somehow of emotional stress (was upset enough to be crying) or the bed not being supportive. I don't know. Just wondered if anyone had a clue what it was. I was initially worried I'd done something bad to the baby, but since it has gone this morning and baby is still kicking, I guess not.
