I'm 22 weeks and although I have always throughout needed a wee every few hours, this is now within the hour I'm desperate. I'm also having to wear pads daily as i seem to let a bit of urine out as I'm going about my day. Last week I felt really uncomfortable needing a lot of wees and a slight burn. I had my sample checked by the GP and it was clear. Today I am so uncomfortable, I have a heavy feeling in my bladder and I'm needing a wee every 45 minutes or so. I keep getting sharp burning pains down there and it looks a little puffy. The pains only started after 7pm and I'm going to call my midwife in the morning but is this normal to need a wee all the time???
