Really hoping someome can help.I started my period on 1st September which lasted 1 week. I was due to ovulate on around the 14th September. I have been taking clearblue ovulation tests which keep showing high fertility but never that i am ovulating. The last 2 days i have had see through stretchy dishcarge and PMS type pains in uterus. I am not due on for another 2 weeks. Could this be implantation?
