Tmi question about AF

Hi ladies, so this time AF was light for 4 days with hardly any cramps, just back ache (I usually have at least one to two heavy days with heavy cramping) but also it (tmi ahead) didn't turn brown?? it just got pinker and pinker, then yellow then clear.

What the heck. Should I start ovulation testing now? I've been done for a day and bd last night (sex tmi ahead)

Still in my fertile window we bd and he said he felt like he came behind my cervix.

Should I start testing for ovulation like normal?
