im in no meds nor in birth control. my boyfriend and i have sex without a condom at first but finish off with one. ive been fatigue, sleepy, hungry (more than normally), little pain in lower back, dizzy at times, nauseous and somewhat bloated. im regular and hadnt missed a period till now. the brown spotting was just once when i woke up and went to the restroom. i havent taken a pregnancy test yet.
