Ok so I have a uti and they prescribed me ciprofloxacin...

Ok so I went to the Dr. For a uti and they prescribed me ciprofloxacin well they told me to take it every 12 hours so I have been taking it at 6:00 am and 6:00 pm , what I am getting at is I been feeling like I might be feeling early pregnancy symptoms before even taking it feeling sick to my stomach and peeing alot and ect. Well I have been feeling sick around 3:00 pm every day Idk if its due to the medicine or not ...any advice would be very apreciated....oh yea I am 7 days away from my next period too.
