thanks TFLS. I can identify with your rebellion much needed break.
Indeed I've heard that ear thermometers are no good for charting. I'm using a fairly cheap digital thermometer, orally - they say vaginally would be better but I can't be bothered. Before I bought this one I collected some info - MyNFP.de (my place of reference for most such things) says that if your thermometer is digital, it is very important that it has two decimals. In your chart you can round up or down (36.77 would be 36.75, 36.78 would be 36.80) but if you have only one decimal it is not precise enough.
Also, I always wait 5 minutes before reading the result, rather than stopping at the peep. I've found this gives me much steadier lines, less of an alpine panorama, IYSWIM. This is also recommended by MyNFP.de.
At the pharmacy, when I asked for a thermometer with two decimals, they also offered me an analogue one which was devised specially for charting basal temps for conception/contraception. It was about 3 times the price, so I was glad I had done my reading first and was confident in buying the cheaper version!
chamois as your bfn was only after 3 weeks, is your ovulation delayed as well (if you don't mind me asking)? Or did you maybe even ovulate before you achieved the bfn? How are things going now?
I brought some herbal teas home with me. Started off with raspberry leaf infusion today. It's supposed to help in the pre-ovulation phase. Later I'll switch to Lady's mantle which assists the LH-phase and supposedly is also used for preventing MCs (also good for assisting ovulation, I read). Though info is conflicting and confusing... and I'm worried: Given that my cycles basically do work and I can conceive, as proven before I MCed, maybe I'll just make things worse by drinking these infusions? But on the other side, it feels like at least I'm doing something... instead of just waiting... which feels good. Ah well. I'll just go easy on the herbs.
Do any of you have experience with herbal conception support? Such as agnus castus which is often used to help regulate (especially short) cycles and reduce PMS; herb robert (Geranium robertianum) which is generally supposed to be good with fertility problems; sage, rosemary, nettles, and the lot?
