I have had a cold for two weeks. I had unprotected sex Saturday and have felt nausea on Sunday and am now experiencing "urinary frequency". I don't have to go to the bathroom all the time, but I can pee and still feel like I have to right that moment. As I said, I am currently getting over a cold. I am on azithromycin. I also stress hardcore about EVERYTHING. It has not even been a week since sex. I have no cravings, only feel mild nausea at one point during the day and have no other symptoms. I am not sure if all my symptoms are cold and extreme stress induced or could be possible pregnancy symptoms so early. Is this even possible?
