We had out of town guests this weekend, so I couldn't buy a test until they left. I took another dollar store test on Saturday, very faint positive again. The guests left a couple of hours ago, so I stopped at the store to pick up some tampons and some more tests. I bought the Answer brand, only because they were the cheapest at the store and I wasn't feeling too optimistic.
It was positive. Very positive. I didn't even have to wait three minutes, and the test line is darker than the other line.
But... my temp was back down to 97.9 (F) this morning. Which is still quite high for me, but considerably lower than my high of 98.2 (F). And I have NO pregnancy symptoms. No sore breasts, no creamy CM (just sticky).
So I think this bean won't be sticking.
