Could i be pregnant? Need answers!

My boyfriend and I messed around on my ovulation date! He came and it was all over his fingers and hands then he fingered me. Could I get pregnant this way? I've been very tired and its not normal for me to be tired. My heads be hurting off and on, my stomach feels weird and if you touch it it feels sore. My pelvic around feels sore as well. Any thing will work! Thanks
