Late period

Hello. The first day of my last period was June 27. I had very light spotting for 3 weeks. Was told it was a yeast infection. After using a cream for three days the spotting stopped. It was very very light spotting. The spotting only happened early morning after peeing when first waking up. Fast forward to now my period has not shown up. I took a pregnancy test a few ago they were negative. Should I be worried about this? Should I call my dr or just wait for my period to come? We are not actively trying for a baby. My cycles are normally 30-35 days. So this is abnormal for me.
