bbt question

I take my bbt at 5 am everyday, but this morning I woke up at 4:09 am got some reason. I didn't sit up or get out of bed, and I fell back sleep a few minutes later. My alarm went off at 5 and I took my bbt. It was slightly higher than what it's been the past couple days (by like 0.1-0.2°). Is this temp considered valid since it technically wasn't taken after 3 continuous hours of sleep? This is my first month charting, so I'm not really sure what I'm doing ? Thanks in advance!
