High bbt for 21 days even though I had my period?

My period didn’t even last a full two days and my flow was lighter than normal. But it was heavier than I’d expect implantation bleeding to be and it looked and felt pretty typical otherwise. I haven’t taken a pregnancy test. I think I’ll wait until the weekend. I rather give my temp more time to drop than deal with another negative. I suspect I had an early loss. I had/have enough pregnancy symptoms that are hard to explain otherwise. I hope I’m pregnant I’m mostly posting this to get it out off my chest but also to see if anyone has had/is in a similar situation or has any thoughts about it. Hey, you can even use this post to get whatever you’re dealing with off your chest. It’s a crazy ride we’re on
