I got a letter today asking me to come for a smear test as it's now due. Ds is 5 months old and so far I haven't had a period, but the letter asks you to come midcycle. Do I wait til they are back to normal? I want to get it done, but don't want to psyche myself up for it (find internals quite traumatic since dd's birth) only to be told to go back a different day. wwyd?
