Anyone still tracking BBT after BFP?

I've kept doing it (I'm almost 5 weeks now) but the last 2 days have had small drops in temp. Still way above cover line though. Have read mixed advice if you should/ shouldn't continue so just wondering what other ladies are doing? I've had 2 mc this year so it was helping me see the constant higher temps but now the dips are worrying me and wondering if I should just stop. Thoughts?
