Menstrual like cramping since 3dpo?

hi girls, my hubby and i have been ttcing for just over a yr now and i was just wondering if anyone has experienced menstrual like cramping since 3dpo with yellowish creamy cm? i'm now 8dpo and today i seriously felt like i was getting af (felt the gush and everything tmi i know) and ran to the bathroom to find it was only cm, my bbs have also been a bit tender, and i have had a couple sharp stabbing pains on my left, headaches and nausea off and on, fingers crossed that this is our month, just trying to find out if anybody else has experienced this and been preggers? thanks girls and for anyone ttcing lots of baby dust to you!
