4 days of positives in a row

[TTC Again]

Hmm, it stayed up yesterday, but then dipped again today (9 DPO) - not below coverline again, but clearly a dip. I don't know what this means, or if it means anything at all. I'm trying to wait it out and not test, but have been peeing on OPKs for fun - not really showing anything interesting though (just a faint second line, clearly lighter than the test line). Giving it a few more days. AF could be due anytime from tomorrow through Sunday (I don't usually have a long LP).

Even if I DO get a BFP, I'm so nervous about having an other MC.
