Am I Having A Cryptic Pregnancy Or What Is Possibly

Am I having a cryptic pregnancy or what is possibly going on? I have had a 2 day of what I would say is my period (lighter and didn't look like my usual period neither any symptoms and I usually get them a day or two before I start) and I have been feeling some pregnancy symptom and I have a 20month old daughter that I have breastfeed since birth and started weaning at 19 months. I had negative urine test and my periods were irrgular for about 5 months before going regular when my daughter was 18 months.
