FTM & needs help!

Hi ladies, I'm a FTM and just a couple days shy of 2 months pp. I am no longer breastfeeding, haven't gotten a period yet & not on birth control yet. My boyfriend & I had sex last night and the condom broke and all the cum went inside (tmi I know sorry). I went to go wipe earlier and there was a little brown like discharge with maybe a drop of pink ish color. I'm also having some mild cramping. What is this? I'm so scared, please help 😭
