Help! What is going on with my cycle?

So, I’ve only had two period since I had my daughter 16 months ago. The other two were like 50 something days apart but this time I’m on cycle day 68. I took a test a few days ago, negative but also the day before I took it I had a very very small bit of spotting which I thought was my period starting but that was it and nothing else. What do you think could be going on?
