Just saw the midwife, she wasn't concerned at all - just put it down to irritation of the cervix & my "bits". The cramping she said is probably BH & the sharp pain is stretching/pulling from belly growing.
I still feel a bit tender but not like thrush so I might ask the GP to do a swab on Tuesday when I see her. It does almost feel like a UTI but without the pain when I pee.

Thanks for your concern ladies
