just take paracetamol for now, if you can. speak to the gp tomorrow abouyt codeine. had to take it with dd2 due to severe back pain, but didnt like taking it (was in the final 4 weeks) as i was worried about the effect on her.
I beleive that codeine and brofen while pregnant can cause breathing difficulties in babies although I think this is if you take it long term. Do you have a 24 hour surgery number you could ring. Or phone the midwife at the hospital and ask them they should be able to advise you. Hope you feel better soon.
