First PP cycle?

Rachael

My son will be 9 months on the 10th of December. I am still nursing him and pumping at work. He is NOT sleeping through the night. He eats 3 solid meals per day and at the end of October I had what I thought was my first cycle I spotted-light flow for about 2 days and then one day of light brown spotting. Could that have been my cycle returning? I should have another period now but it’s a no show. I am not pregnant. How was everyone’s first cycle after delivery?
