I am confused here, I had my menstrual on Oct 3rd and my BF and I had sex on Oct 11th.. On Oct 28-29th I was spotting, light pink and on the 30th nothing and the 1st of Nov it was just a brown spot. I have been experiencing lower abdominal cramps, leg cramps, my middle finger went numb. My stomach has been bloated, I have been full of gas and constipated, have blue veins in my breast and my nipple area is getting darker..I have taken two pregnancy test one had a faint positive which was EPT and the other was a generic brand which said not pregnant..I'm not sure what really to think but its too early to determine. My cycle is every 28 days like clock work and I am now 3 days late. Wondering if my levels are too low to detect now and can my OBGYN detect signs of pregnancy in my uterus doing my pap exam?
