So ive been feeling really naseous and having headaches and light cramps lately. I just stopped my BC in October and i thought it was side effects from that but ive been told they dont usually show up a month later. I had to periods this month due to my body trying to regulate. I dont really keep track of when i have sex or ovulate because im not ttc but if it happens it happens. Long story short, glow says im not supposed to start my period until Dec. 11th. And im only 2dpo from my last period. Took a test just in case and was bfn. Possiblility of being pregnant?
