Implantation cramping?

Aubrey

Hey everyone! I’m new to the app. This is my first month TTC with my 2nd child, and I noticed Wednesday (today is Fri) night I had cramping all night and all day Thursday but I’m not supposed to start my period until Tues or Weds. Could this be implantation cramping? I feel like it’s too early for period cramps. Also when should I test after these cramps? I tested yesterday and was negative. Thinking of testing again tomorrow.
