Hello ladies, today is the day of my expected period, last night I was cramping and I put on a pad cause when I wiped there was a little bit of pink blood, when I woke up this morning there was just like brown blood

Well I took three tests just to see

Can I trust all these 3 tests??

Also this is what I wiped this morning, is this my period starting?? I am on the pill so idk my period was lighter last month too
