Constipation relief?

Samantha
Hi ladies! I'm 5w5d and this is my first pregnancy (YAY🎉🎉🎉)! I've had ongoing cramping since week 4 which I've read is normal, but I'm having stronger cramping now and I believe it's due to constipation as my bowel movements have definitely not been regular (also read this is normal).  I've seen mixed reviews on rather miralax is safe for use... so my question is what are you using that has been approved and helped you find some relief?!Â
