I had unprotected sex this Sun. morning, it was my first time for intercourse ever. I'm 34 yrs old and sadly it was w/a guy I barely know and nor care to see again. I got the Plan B One-Step pill about 14 to 15 hrs. afterward. I now have a foul vaginal odor, some irritation, slight itching along w/what feels like discharge, but nothing comes out. Also have at times what feels like slightly passing gas. I've also been very hot at times, primary in the morning, then it goes away. It's been three days now and made an appnt to see a gynecologist Mon. since I'm concerned I have a yeast infection or UTI from either the pill or intercourse itself or both. He said he didn't come, but can't be sure and precum could have come in me so I'm trying to be precautios, just wish I had done that before. Please, any info. would be helpful. I'm wondering if doing a pregnancy test Mon. will be to early since I started my period on Aug. 30 and shouldn't start again 'til Sept. 27 or so. I also had previously incontinence issues from a bad fall in Feb., which has led to knee issues as well. I'm 280 lbs., 34 yrs old, single and scared. Any info. would be helpful, thank you.
