Could I be pregnant?

My husband and I have been TTC for a few months now. Normally a week before I get really sore boobs and then 2 days before AF I get cramps. This month has been different so I’ve had light cramping for the last week and starting yesterday my nipples have been a little sore but nothing like it normally is. Could I be pregnant? Or am I just turning every PMS symptom into a pregnancy symptom? Lol I’m just scared to test and get a negative.
