I've been experiencing period pain-like cramps in my lower abdomen on and off since yesterday evening and they've grown more intense tonight - coming in waves. I went to the doctors to get checked out for a UTI this morning, but he thinks it's unlikely. He didn't seem bothered about the cramps as there's been no bleeding or excessive discharge so far. I had aches earlier in my pregnancy, but they weren't this strong. Just wondered if anyone else had experienced stretching pains at this stage in their pregnancy or should I be contacting the midwife tomorrow?
