HELP PLEASE! Haven’t ovulated, but bleeding like period?!!

Can anyone please help me out with why this may be happening! This is my second cycle after a 12 week miscarriage in Nov. I ovulated Dec 8(cd25) and had a normal period Dec 23(after a 38 day cycle). My cycles were around 26-30 days before pregnancy with ovulation being between CD15-20. Ok well this cycle is confusing me and freaking me out bc I’ve been waiting on ovulation and tracking my bbt and it hasn’t happened yet which it still could be a little early as I’m on CD 19. BUT what is freaking me out is I started having pink spotting yesterday morning..which turned into red and a little more than spotting. I woke up this morning and took my temp and it was 97.02 😳. I thought my thermometer was broken!! My temp went from 97.35 yesterday all the way down to 97.02!! A big dip like period is coming..and it’s not due til January 19 give or take when ovulation happens. And I’m still bleeding! Now it’s more like a light period starting and it’s a dark red/purple almost color but I’m not having any cramps. What could possibly be going on?!? I’ll post a pic of my chart below. But my app has not pin pointed ovulation and I don’t see where it could have happened I don’t think. Anyone have any ideas about this?!? I stopped my BC end of June and got pregnant in September. Ovulation and periods have been normal until now and I’ve never had any spotting or bleeding between periods, besides the spotting during pregnancy a couple times, then my miscarriage. There also seems to be a slight odor down there now with the bleeding, it’s not fishy, more like a vinegar smell almost. Could it be an infection??
