Possible pregnancy?

Just recently hooked up with my new man an well one thing leads to another an well ever sense last Thursday night was in the time of the fertile cycle period he has been busy. Well needless to say we had multiple times on Sunday an that was my ovulation day. Now as of yesterday I can not taste Pepsi an I love Pepsi. Can not drink beer either. Umm stomach upset an want too puke at times. When I do there is nothing? Breast nipples hurt a bit too. Period to be in January around the 5th. When she I take a pregnancy test? Oh an some cramping too?
