What the heck?

I have irregular periods got it last month and this month on my expected date which was yesterday I had Light pink only when I wiped and this morning a light brown discharge. I had very light cramping not like I usually get. I always break out on my chin same time every month around when I’m suppose to get my period but this time my skin has no breakouts! Anyone ever experience this and get a BFP? Yesterday’s test was negative. When should I test? I have no other symptoms at all then the on and off light cramps and brown discharge.
