Cylce day 32...no period?

I am now on day 32 of my cycle and still have no period symptoms. I woke up this morning, vomited and then took a pregnancy test which came out negative. My cycles range from 28-31 days, my longest was one at 38 day. Should I wait to see what happens or take a pregnancy test in a week or so? I take Xanax so if I am pregnant I don't want to cause any issues. And I do have an appt. with my OB-GYN in 2 weeks, was just curious as to what ya'll thought. I have been experiencing "pregnancy symptoms" but those can be period symptoms too so...idk.
