Hi ladies
I have been ttc since Dec 2015 - I have PCOS and a slightly crazy cycle that can be anything from 28 days up to 50 days plus on occasion. I took clomid for one cycle CD 1 -5 last month, and then I saw a new consultant who wanted more blood tests and more monitoring arranged before I took it again.... so this cycle I am clomid free.
I am on CD 19 right now - we dtd on CD6, CD9, CD13, CD 16 and we were planning to go again this eve lol
However, on top of a rotten head cold (attractive, I know! 
) I woke up with a really sore lower back this morning and I have been spotting very lightly today, like a light brown.
I don't usually use OPKs so I don't have any in the house to double check and I know they are not always very reliable if you have PCOS. So I am wondering - does this sound like OV (there's no EWCM), potentially implantation bleeding, or just mid-cycle weirdness to you guys??
Thanks!
