Welcome, HopingCarter!
How exciting that you see some lines! I also recommend the First Response Early Response, as they have a great reputation, and also my favourite is the ClearBlue Easy Digital that says "Pregnant" or "Not Pregnant" and tells you how many weeks since conception you likely are (1-2, 2-3, or 3+). I had trouble deciphering between evaporation lines and faint positives before, so seeing the definitive answer in words was awesome. That is the kind I am going to use tomorrow!
It is taking willpower to not test for sure! It's a couple factors... One, I only have one CBED with the weeks indicator (I bought the wrong two-pack; the other one in the pack is just +/- lines) so I don't want to waste it by being a little too early. The other is, my husband wants to be with me when I test, but he leaves for work earlier than my alarm is set to take my bbt. I don't want to throw off my bbts by being up an hour early, and throw myself into a panic because they are lower than I think they should be (I did that a bit last time). Tomorrow I'll get up with him and just forego the bbt for that one day, but I wouldn't want to do it a few days in a row. I guess I'm just a little neurotic about it, lol.
I contemplated testing tonight when I get home from work, but I remember doing that last time, at 12dpo like I am today, after a 7 hour hold (that was hard!!!) and it was a negative or perhaps an incredibly faint positive. I felt really down after that; my moods had been crazy that day! But then, with my FMU the next morning, at 13dpo, the CBED was a positive, which was a big relief.
I think it's going to be hard to sleep tonight!
