I'm really struggling financially (lost my job at 8 weeks and won't start my new job till end of august when I'll be around 20 weeks) so I can't afford to buy maternity clothes or bras. I'm managing with my normal clothes so far but I'm having to squeeze my larger and rathe tender boobs into my normal bras. Will wearing slightly too small underwired bras for another couple of months till I'm less skint do any harm?
