Sounds wise to call them in the morning then, well done for thinking of NHS direct, I forget all about them! lol
Also glad the drugs are ok, I was warned off codeine - i have them for my back but was told not to take them. Funny how they differ eh! lol
I had sharp pains in my left hand side / groin area and had a scan at 6+3, so all is not lost hun, all was fine with me, I'd strained a muscle that was all, so really hope it's the same for you, or as you say a urine infection.
((hugs)) have you got someone to keep you company in the morning? a friend or relative?
Will be thinking of you x
