Flirting Via Social Media. Is this a legit concern or am I just being sensitive because I'm on my period.

My boyfriend and I have been together for 6 years now. There have been situations in the past in which social media became an issue. Today I happen to stumble across some emoji flirting. I haven't mentioned anything to him yet and I'm debating as to whether I should or not. Am I just being extra sensitive because the red devil is living inside of me right now and I'm thinking with period brain? Or is this a legit reason to feel bothered? Help a sister out!!!
