Trying to conceive

Hi ladies..

im new to all this but I was wondering if anyone has experinced the same, I'm 2 dpo and this morning iv woken up with a sore back (the bottom) and belly ache type cramps but also noticed lastnight like a weird flutter/bubble pop that's the best way to describe. I have a 2 year old but I can't remember experiencing anything like this with my daughter thank for readying xx
