I haven't used it myself but there have been a mix of answers, if you are struggling you could use dulcolax I have used them since the second week and find they work a treat I take one a couple of times a week, hope this helps
I got it this week and have gone more and it was a much gentler experience - not too gentle though it's not a laxative so may take a few days to kick in but for me it seems to have made things easier x
