Pregnant?😭

So I haven’t had sex since October we used a condom and he pulled out. I got my period on time and regularly and then the next month it was 4 days late (maybe due to stress I believe I ovulated later) but my periods are ALWAYS regular. and the jan one was 2 days early and lighter than usual but still had clots. And I’m freaking out bc I read online of something called a cryptic pregancy.
