Went to the doctor

I went to my doctor today, and told him I been having sharp pains, and watery discharge, he told I have an infection, and I asked what it was, he said bladder infection, I also had a pap smear, he told me my ovaries were probably ovulating right know that's why I been having pains, but my period is April 2nd, he also said I have a very sensitive bladder, they handed me my paper work, and I'm a nosey girl I looked through the stuff he put a x by, he put one by Chlamydia so if I have that why wouldnt he tell me that? But anyway I just went to the bathroom, I went twice before this time and wasn't spotting or anything but I see little pink stuff, just like yesterday night I had a little pink on my tissue paper any thoughts??? I took a dollar store cheapie and it came out negative, but my doc said of I keep having tummy pains he's gonna do a ultrasound and he's gonna see me know next week.
