Is it possible?

Krystle • Happily married DD 1/21/18 #2 due 4/2020
My husband and I have been ttc #1 for 2 1/2 years. The last 2 days I have had light spotting, only when I wipe, and Monday I had some pelvic pain, short bursts lasting only a few seconds. My breasts also feel very full and sore and I'm having some nausea and fatigue. Period is not due for a few days. Is it possible this is implantation bleeding/ pain?
