I’m hating being hopeful

Sappy

I recently started bleeding last week, like moderate spotting (couldn’t fill a panty liner but there were dark strings of blood in the toilet the first day) for 2 days and then spotting brown for 2 days. I thought it was my period because I ovulated on the 1/27 or 1/28 but I feel quite nauseous. Is this all in my head or should I take a test?
