Ohh I hear you with the no more in September, my month is May. There are 4 grandchildren on my DH's side that are May babies and if I didn't have a miscarriage in October it would be 5. On my side of the family we have 3, would have been 4... busy month!

I am currently in the same situation as you, I had very light spotting at 7DPO and today at 9DPO I have more but it is heavier, we only DTD once and according to FF it was on 1DPO... maybe it is wrong this month

Best of luck, I hope you get the result you are wishing for xx
