Is this implantation bleeding?

St

So I’m a mom of an almost 2 year old and I never experienced implantation bleeding with her. I’m currently on medication to help with my PCOS to help my cycles go back to normal as my period was so off due to stress in 2020. My husband and I had sex for the first time in 6 months 7 days ago as he was deployed. And I’m tracking my ovulation to make sure my medication is working and it is because I’m ovulating this week according to the sticks. I’m not supposed to get my period for another 1 1/2 weeks and I spotted last night day 6 and now this day 7 after sex .... I’m kinda excited as we do want another baby but unsure if I should happy bc I know there can be ovulation bleeding from what I read ... help ladies I’m lost and sorry for the lengthy post haha 😂 just need y’all to know the details of everything of why my mind is going down the rabbit hole.
