this past month of my I had sex on the 11th but around the 16th I went to go pee and my urine was the same normal color but when I wiped I noticed pinkish on the toilet paper this happened the next day as well but it would only happen when I would go pee and it was very little pink spotting then later I got my period on the 22 lasted about 4 days but im scared there might be a chance I may be preganat? Im only 19 and no longer with him
