Hello! I am a 25 year old female with irregular cycles. I have been mapping my cycles for the last few months to see when I may or may not be ovulating. We weren't trying for baby right now, however I feel I might be pregnant. I have been feeling dizzy and super tired lately. Along with those two prominent symptoms I have been feeling a heightened sense of smell, tastes are a little off, runny nose, headaches, twinges in my lower abdomen, brown spotting with no actual period. I am on day 40 of my cycle. I took a home pregnancy test on cycle day 33 that came back negative. Could it have been to early to detect?
