Breastfeeding Worries

Hi everyone. I'm a first time mum to be (baby is currently 3 days overdue). Have tried hand expressing as i heard that it can kickstart labour. Tried all the tips like heating and massaging breast beforehand but I get at best just a slight dampness at the end of my nipple. Has anyone else experienced this then gone on to breastfeed okay? Or is this a sign that my body isn't actually producing colostrum? Really worried that there could be a problem.
