TTC 12 days late, too afraid to test

I’m currently 12 days late which isn’t always something new to me. I’m not diagnosed but I have a suspicion of having PCOS and I’m only 21 but since the day I started having periods I have never been regular. I’ve always had longer 30-40 day cycles and would stay pretty consistent with that but every once in a while I’d get a 60-80 day cycle. Over the past couple of months after getting my implant removed I got a 28 day cycle right out of the gate and I was so excited. But low and behold it’s gets further and further apart but I have been staying closer to 35-40 day cycles without a random long cycle. I don’t really know the point of this post but I just felt the need to share everything. Maybe get some opinions and courage to test bc I’m so tired of being let down. I haven’t been tracking and was gone on vacation with the girls the 2-9th so I don’t feel super confident but I have been having twinges, pulling sessions some mild cramping off and on and hella bloating. I have small boobs so I never really get big swollen boobs for my period , maybe some slight nipple soreness which has come and gone already. Other than that I feel pretty much the same, maybe it’s a good sign. Everyone stay safe 🌻 -mac
