Implantation bleeding or period?

Bri

I have no idea what implantation bleeding looks like. I was on bc for ~10 years and got off early December. My cycles have been 26, 30, and 32 days since.. I’m almost on cycle day 38 with no period yet. Severe mood swings and crying spells the last two days. My boobs have been tender for about a week. I usually don’t get THIS bad if mood swings and never cry. The first time my boobs have ever gotten swollen and tender was last cycle. I’m lost on what to think. My SO was out of town so we didn’t have sex this month until cycle day 25. So idk if I ovulated late and chance of pregnancy (PRAYERS, we’ve been trying), or if my period is coming?? :( any suggestions?
