Hey Renee, your chart looks much better with the FF CH. It's a slow rise but definitely rising. The temp dip after the O is hopefully signs of implantation dip.
You've heard that some people get a +HPT at 7DPO right? Well, not everyone will get it that early, so you're still fine. Wait a few more days to test, or you can test daily if it makes you feel better... I wish you all the best. You will be a mommy soon.
