this morning I went to the bathroom and there was nothing there. after I got to work I went to the bathroom and saw like a pea sized amount of light pink something in my undies. and when I wiped there was a little smear of light pink. yesterday I woke up with really sore nipples, but not sore breasts. what is strange about is that I never have sore nipples, like ever. I also felt a strange lump I've never felt before on the right side of my right breast. I've also woken up with a strange metallic taste in my mouth a few times. my period isn't due until next week, but a little over a week ago I had what felt very similar to period cramps, just a little milder. I have also woken up feeling sick, I have even gotten sick a once or twice but blamed on light drinking the night before. sometimes when I pee I feel a light pain in the lower right side of my abdomen.I've been complaining about my different symptoms to my mom, and she's is starting to think I sound pregnant and I'm getting really worried.What I might also add is that I have been on birth control for over 3 years but earlier this month was put on antibiotics for a bacterial infection.Based on what I've said does it sound like I should begin to worry? Does it sound like I experienced implantation spotting?I already have a ob appointment scheduled for 2 pm tomorrow, and I'm gonna request a blood pregnancy test. I just want to get some opinions from other people who have first hand experienced this.
