Pain and cramping 4weeks 4 days

Lianne
Hi guys my DD is 30th November so currently 4 weeks 4 days. I've had intermittent cramping in lower abdomen and the odd sharp twinge also daily lower back pain pain when I walk. Also very sore boobs and nausea. Going to have an early scan next week to make sure everything's where it should be but ob/gy said it can be completely normal. Fingers crossed but can't help but worry. Any body else experienced similar? X
