Sunbathing, I understand the kind of troubles you have with both the irregular cycle (mine vary from 22 days to 34/36) and the libido-less husband. On my o-day my husband bonked me but couldn't [wouldn't] finish and left me feeling like I'd pretty much raped him! It's a horrible situation to be in and I think it makes things THAT much harder.
I reckon this month it was as you've suggest and you geared up but didn't quite get going. What GrandHighWitch says is perfectly plausible though - I really hope the HPT goes the way you want it to!
If not, I really recommend taking basal temperatures to help you understand what's going on - this is my first month doing it and I've found it seriously insightful. Not only do I know when I ovulated, but I also know that I absolutely did - because my temperature raised and stayed raised! It's really reassuring and something I didn't really know I was worried about!
I'm on 11DPO today and have started to feel sore in the ol' nipples. I've had quite prominent veinage on my boobs for a few days but I know I've noticed that before despite not being aware of when in my cycle it was, so have paid it no heed. I did a test first thing this morning and it was plainly negative.
I was talking to my husband earlier and we were talking about goats (a mutual love - we both volunteered on a goat farm in Australia which sounds really weird unless you know the context!) and some how wound up talking about pregnancy. (One of the goats we bottle raised got a bit frisky before she was even a year old and found herself upduffed. The farmer had to give her a forced abortion or risk losing her.) He asked me how I would know I was pregnant. I said "Well, either when I get my period I know I'm not, or when I get a positive test I know I am."
He asked me when my period is due and I said "yesterday." He gave me an excited look so I very quickly reminded him that I have an irregular cycle so could be waiting some time yet but he got me excited, and I decided to go do another dip test.
I haven't been able to get a good photo, but I have a (very!!) faint positive! But where any tests I've done before have been totally white on the background - this ISN'T! It's pale but it's in the right place and it popped right up within two minutes so it's not an evap line. You can't see it very well on the picture I took at all, but it's definitely there when you look at it right in front of you.
I cannot wait until tomorrow morning to see if I get a stronger line!! I don't want to tell my husband until I'm certain.
