A little advice for round 3!

[Aleelilook]

So I've been waiting for my second AF after our mmc, and here she is, rocked up on time for the second month, well done AF! However it is rather light, and a bit brownish (sorry tmi). Anyway I don't know whether to phone the clinic now as they aren't open on Sundays to book a scan for Monday, or to wait? I don't want to miss my chance of starting round 3, but it's gone from spotting yesterday, to just a tiny bit more now! It's always the same, when we want the sodding thing to turn up it's a bloody pain in the arse!!
