I’m 33 weeks and this has just started happening in the last week. I’ve been trying not to sleep on my back and stay on my left side as much as possible, but I’m generally really tired so I take the odd lie-down in the day. Sometimes I’ve noticed my leg feeling numb and tingly, which I’ve heard can happen when you lie on your back. Has anyone else experienced this? I’ll ask my midwife about it when I see her next week
