Last month, I ovulated on CD 21, then oddly only had a 28 day cycle. This month we've decided to not try as we have a ski holiday booked for my husbands 40th. Obvs if I was pregnant I'd be over the moon but decided to relax about it and use protection around my fertile week just for one month so I can ski! Currently 4 months TTC.  

This month, no OPK used. temp peaked on CD11, didn't think anything of it, as it wasn't as high as prev months peak temp at ovulation, which we're backed up by OPK. Temp came back down, then spiked again at CD20 which i thought was ovulation. However CD22 I started spotting. Brown discharge. Hasn't really turned into a period, has continued being brown and has only been heavy enough for a tampon on 1 day, and even then it probably wasn't really heavy enough. Now CD26 and I don't know whether that was my period or not, but I'm still getting brown discharge. 

We only BD without protection on CD9. Could I have ovulated really early, 2 days after we BD and this could be IB? 

Argh! No idea what's going on! Any help would be really appreciated! Thank you
