bfn and confusing chart w/ spotting and big dip. help!

M
Going crazy 😩 so this is my first month charting and I though I ovulated on cycle day 9? Which would make me 8 or 9 dpo, then I had a huge temp tip yesterday and now pink spotting this morning 😩 my cycle was crazy messed up last month and my period was over a week early (started as light spotting but ended up full in bleeding af) but that was following what we think was a chemical pregnacy. I guess I am just scared that something similar is happening again this cycle. 
Do my temps indicate anything? Super unsure right now! Any one have something similar happen to them? Advice from experienced people much appreciated! Looks like bfn to me but poss OPK 🙄 am I out again this month?
