Hi Tayahs Mummy
Apologies if I don't use correct / any acronyms as i'm new to the site I don't usually have any mid-cycle spotting or bleeding but I do have long cycles (35 days plus). in June at the time my temp peaked I had 2-3 days of spotting, like you just on the loo paper and pinkish. Didn't think a lot of it, was more suprised when I got a suspected period about 10-12 days later as it was only day 23 of my cycle. No reason to suspect pregnancy as my temp was all over the place.. Figured it was just a really short cycle and started cycle count again until I got to 42 days last week and carried out a HPG - well 5 actually - all of which were positive!!

Having researched it & asked questions of people since, it seems that spotting at O and then a seemingly short, light bleed at implantation isn't uncommon & that I won't be the first to mistakenly suspect I'd had a period

So I could be wrong and I just had wierd unexplained bleeding (I'll found out if it was an implantation bleed or an actual period when blood test results tell me how far gone I am tomorrrow) but it seems that I had the same as you and it was an O bleed and that I may have conceived at that time..

Hope that helps ;-)
