TTC, ovulating and bleeding. ADVICE NEEDED

Hi everyone, looking for some advice, help, thoughts etc. I had a chemical pregnancy back in September when we tryd but come October I got my period after two weeks positive test. November came and my period was late (was praying I was pregnant, but I wasn’t I took a ton of test) so my period finally came December 2nd after two weeks late. It was super super light. Never had a period that light & it only lasted 3 days. Didn’t even need to wear a pad or tampon. So now I start tracking my ovulation praying I ovulate (so we can try again this month) since my period was off and soooo light. So I started ovulating last week. December 15-18th I was HIGH. Yesterday and today were my PEAK days .... we only had sex on the 15th.... soooo now come today I start with cramps and bleeding. I feel like I have my period... lower back pain, small cramps and blood. The blood is pretty light and not chunky and no clots (I did take some pictures I’ll post if asked to see). I also took a pregnancy test a few hours ago just too see and it was negative. I also took a ton of pregnancy text when my period was last in November and all negative. Can anyone tell me what they think is going on? Or if they have had something similar. I am currently ovulating.. how could I now have my period? Help 😫😫😫 Also my next gyno appointment is January 19th. So still about three weeks away.
