Implantation or early period?!

We’ve been trying for years. We had our son through IVF and starting to explore our next IVF cycle. Natural pregnancy is unlikely for us, we’ve been told.

I’m not due my period for another 6 days. If I’m ever early, it usually only by a day or a day late. Last night, went for a wee and got a pink tinge on the toilet paper. Happened for a few hours and has now stopped. Usually before a period I can get this but it continues into a full flow, not stopping, and is never this early.

Anyone else experienced this?! My fertility anxiety and sheer hope are playing tricks on me

*should add we experienced a miscarriage with our last IVF cycle
