Implantation pain????

Elaina`sMama • Got BFP on 11/18/15 with baby #1 - she was born on my birthday, July 25, 2016. Planning to start trying for #2 in July 2018 😊😊😊
So I normally get very mild ovulation pain.. A small pulsating feeling on my left side around the ovary. Well I am 6-7 dpo (used first response ovulation tests) and just started to get a similar slight pain in the same spot. Could this be implantation pain?? My boobs are also a little sensitive today. AF is due a week from today.
