Ever since I was 12 my cycle has lasted 4 days I'm 29 now and been ttc for almost 3 years. For whatever reason last month my cycle came a day early (just light spotting) and lasted a total of 20 hours. I got my hopes thinking we finally got pregnant but no I tested to the 10th and got all negatives. Now I'm in tww (7dpo) and been having light PMS type cramps and now I'm spotting again. What in the world is my body doing?
