Should i test or wait for AF to come?


My period is late 6 days had sex two times one after i had my period in February & then in March before my period but after my fertile window. I have been having nausea through out the day and loss of appetite and my nipples are slightly sore. I also read a 37 day cycle is in the norm and that would be on Wednesday for me since my last period should i test or wait? I have never been pregnant so i dont if the symptoms i have are pregnancy rerelated or some other health concern😬😥
