Anyone❓❓

I've been having dull tiny cramps all over my abdomen for these past days & dull aches on the two ends (each side)  of my pelvis & lower back pain which started yesterday. My period doesn't even start until May 22nd . Me & my SO had sex during & before ovulation but was using the pullout method he accidentally came a little In me & this is what I've been experiencing ever since . What could this be ??
