Should I test??

So Me and my boyfriend had unprotected sex while I was ovulating and he almost came in me but he says he held it in but while he was still in me he was pulsing so I don’t trust it, and two days later like at midnight clear stuff came out and like darkish/light brown gelly stuff came out and for two days light brown discharge came out. It’s now been 2 weeks and my whole body has been sore I get sharp lower abdomen pains, back pains I’ve been having really bad migraines, and just random cramps that come and go I was suppose to get my period yesterday but it didn’t come?? Any suggestions?
