TTC beginner

Just trying to slim down my list of possible symptoms. About 2 days after my period, my boyfriend and I had intercourse. 2days after the intercourse I started having dull cramping. Now it being 9 days, I feel pressure that goes from the left ovary to the right and tugging/muscle tightness in my lower abdomen. I got my implanon out in August and had a pap smear that day and my OB said everything is great. I was just wondering the chances of my symptoms being implantation symptoms? Any advice is welcomed!
