Implantation?

Cheyann

My period was 3 days late. It started 14 days past ovulation. The 23rd of Nov. It lasted for the regular five days, but was very light all the way through & no clots. I only had cramps for one day, plus fatigue, had 1 time of acid reflux, dull feelings/ pain in my back tummy, side, mood swings & nauseated. It never progressed as the days went on. Im usually cramping by day 1 2 & fading by the 3rd. Negative test the day after bleeding stoped. I have no one else to help me with guidance. So if someone has a thought on this please lmk. It would help. When should i test??
