Can this really be?

I had my little guy May 2018. I am breastfeeding and I got my period again for the first time October 7th. I got my period Nov., Dec., and Jan. I didn’t get my period this month and I just thought it was bc I started to increase my pumping throughout the day In the middle of January to help build my supply some. Today I just felt super tired and something in the back of my mind told me to take a test. I took one and this this is what I got! This may sound like a stupid question, but there’s no way this is from just increasing my pumping right?! This pretty much means I’m pregnant again right? I am just freaking out because this was not planned (my husband and I were done) and honestly, I have zero idea how this happened bc we were being careful, he was not going inside me at all, so it must’ve been from precum. I have a blood test tomorrow but I was just curious if anyone has experienced this or if anyone else has gotten pregnant from precum.
