yes this is normal. You seem to be drinking enough. If it gets really bad you could take some sennakot or dulcolax(some ppl say u def need to be near a toilet after takin this) tbh ive never tried it. You can get the PH and have then every day and that will help or the fibre89 from your cdc that leah was on about. Dont let it go to long because from experience it is painful!! sorry if tmi!!
