I was supposed to start last Wednesday, my cycles are ALWAYS 26-28 days. I had my normal PMS symptoms, moodiness, back pain, gas and sore boobs. Well Friday I started to spot, which is also not normal when AF shows she hits me full on. Saturday was what I would consider a light flow. A few clots but barely any blood. I didn't even use the entire day. Yesterday, back to spotting. Today nothing. I took a test on Saturday and BFN. Today it was BFN. My boobs are still swollen and sore, my back hurts, I have nausea and slight pinching pains in my uterus. I am going crazy as this is not normal for me. Hubby and I have been ttc for 4 months. Anyone been thru this or know what it might be?
