Can I gotten Pregnant ?

Quick story.... I had my time if the month May 9 - 16 then Hubby came home and we went off to Vegas for the weekend of 23-27 of May... We had non stop unprotected SEX even went for twice in a day. .. one of the night we got so tired we literally fell asleep and left you know what down there for at least 10 min. ... Is there a chance I could have gotten Pregnant?? Also when should I atleast check ?? My husband is really counting in it but knowing me my cycles are all over the place it's hard to say if I even ovulate.
