Hi, so for the past 2 days I ve been feeling nauseous on and off, mostly just today, and I ve have brown spotting, but when I wiped after peeing it was sticky and brown. I m on the pill , and I should have gotten my period yesterday, but that is when the brown spotting started. I have been on the pill for about 4 months and I have yet to have my period come when it is supposed to. I ve had sex with my boyfriend without a condom, but he has pulled out way before he would have cummed. I m not sure if the nausea is me being stressed because I absolutely do not want to be pregnant. Please help.
