cns: It's hard to say 100%, but I'd say probably negative as it looks slightly lighter than the control, but like ever so slightly, so possibly still positive? I know I'm absolutely no help with that

I think I'm going to make my final decision as still positive, but I think you had your peak Saturday/Sunday (if there is such a thing with IC).
I think your temp rise looks good especially when taken into considering with cm and cp. I'm guessing your chart looks good for O on CD 14.
The pains I usually get that I'm assuming are (or maybe aren't) O are on my sides in the hip region towards the front, but I've never been sure if they've been O pains or not.
For my stuff, this is all pretty new. I've had irregular cycles before (but I'm talking like light spotting maybe 4 times a year several years ago), but I was also weighed significantly more and once I reached about the weight I am now, my cycles became regular. Irregular cycles didn't start until I got the IUD in at the end of March this year, but as it was non-hormonal, I don't know if that could've really done anything and it was just coincidence as it coincided with increased stress and lack of sleep.
I was actually pregnant twice before DD. It was a previous long term relationship. The first time was November 2007 and had a mmc and needed a d&c (no known cause or anything). Second time was November 2009 and had a mc, but I also didn't know I was pregnant until I started having a mc as I had no symptoms and weird light periods and spotting which I thought was just my cycles being irregular again.
Third time was DD with DH. With her I thought I was too far into my cycle to get pregnant. We got married on CD 21 and that night decided whatever happened, happened. The next day DH and I talked about actually ttc. I bought a bbt thermometer CD 23, took my first temp CD 24, temp spike CD 25 and temps remained up from there on out and got a positive around 13 dpo. U/S put dates to CD 21, our wedding night, but I really think I didn't O until CD 24. But essentially no trying.
With DS, he was an oops. At our age you would've thought that we would've known better than using withdrawal method as birth control. I was checking cm and cp, but that was more just so I could understand my cycles, and I honestly had no clue that I was O'ing based on cm or cp. Like I had no fertile cm and cp certainly wasn't SHOW or anything and I don't remember having either shortly after -- Ultrasound put dates on that day. Obviously could've O'd at some point after, but that was the only day we had sex around that time and had a strong positive around 18 estimated dpo (CB weeks estimator lined right up too). Obviously that's not exact confirmation lol but either way he was an oops with absolutely no typical signs of ovulation around then.
I didn't document cm CD 8 or 9 because of the BDing, and it's just way too hard for me to tell, so I decided to spare myself the confusion and not worry about it. CP was medium across the board CD 8. I was doing some opks, but I didn't really pay much attention to them. Nothing screamed positive anyway. I had some darker ones, but nothing near the control line.
I did take soy isoflavones between CD 3-7, so I don't know if they could've caused some increased temps afterwards or not. So maybe fluke temps from them? My last dose was in the evening on the 21st. I'm hoping that this is just upcoming O. Honestly, I've been wondering about PCOS though. I've read where people have had no issues ttc before, but then are diagnosed with it later.
I don't know how stress changes bbt, but that's really the only thing that has changed over the last 2 days. The last 2 days have been insanely stressful. Saturday not as bad, but yesterday was awful. DS is teething pretty hardcore right now, and then add in constipation yesterday. He screamed pretty much 24/7 yesterday. He got a little better after he finally pooped some, but was still a miserable mess. Then to make it worse, DD was in a foul mood yesterday and a good majority of the time we had both of them screaming and crying non-stop. So yesterday was just lovely. Not sure if stress makes bbt go in one direction or the other, but that was the main difference.
I still have a lot of school work to do today, but I'm trying to keep today as low stress as possible. Even if I've not O'd or am starting AF, I need to try to get my stress levels under control as I was doing pretty good with that before.
Another novel... sorry!

Just a lot of back story and other bits of info.
