Hi everyone, I'm new to mumsnet so please bear with me! I came off the pill on 01/09/17 and started my withdrawal bleed on 05/09/17. DH and I have been TTC and I believe I ovulated on 20/09/17 as I used OPKs. We DTD many times over the week leading to, on and after ovulation. I've had some very light brown, watery discharge (Sorry TMI!) since yesterday and I have done a few IC tests which were bfns :(. Is it likely I could still be pregnant and this could be implantation bleeding? Or is it AF paying a visit? Would a First Response test be worth a go now, or should I wait? Any past experiences or advice would be so helpful thank you! :).
