I don't know what to think!???help me out! Please please please! (TMI).

Trace • I have a 18 y.o. Boy. 14 y.o. Girl. Ttc since 2015. Miscarried Mar 2016/May 2018/Oct 2019/Apr 2020/Apr 2021/Nov 2021/Aug 2022/Dec 2022/May 2023. Ttc our 🌈 baby.
Ok so had tubal reversal surgery November 5th 2015. Finished my last period November 4th 2015. Yesterday night at 2 weeks late for my period. (tmi) I started to have watery brown blood light no cramps nothing and I have brutally painful periods. Woke up this morning it's heavier but still brown no cramps or pains of any sort. I checked glow and we've BD 6 days previous to yesterday and 12 days. And some I between. Could this be implantation???? Or my period? I have no way of knowing the difference at this point. So far its medium flow only wearing a panty liner. I've never had water brown blood before period usually just heavy start right away with horrible pain and pressure down there which I'm not currently having. Just don't know what to think 🤔
