G:3 P:2 last baby is 6 now.

I got off birth control (mononessa) after 2 years in June. We’ve been not trying but trying since then with no luck. My cycles have been regular since getting off birth control and I’ve been tracking them, taking prenatals, and using essential oils. I exercise regularly and eat a fairly healthy diet.

This month my cycle came 4 days early. Starting with pink spotting late Friday night. Saturday i had a light/medium flow and today back to spotting but bright red. I’m having some cramping on the left side. I took a test earlier last week and it was negative (about 6 days before expected period) Should i retest tomorrow morning? Is there a chance I could be pregnant?
