period and pregnant?

I ovulated on the 6th and af came on the 14th (which sucked for vday) that would mean af came 8 dpo I had sex on the 5th  6th 7th 9th and 10th and this period started out at what I thought was ib because it was light pink and only when I wiped the 1st day then the 2nd day it was extremely light pink mixed with cm then on the 14th af was here and this period has been like no other, it's very heavy like some clots but other than the clots it's real brightly colored, I've gotten sick once, headaches like whoa, low tolerance for sweets, and extreme insomnia, like not falling asleep till finally 1-3 am and waking up at 7 am and then falling asleep on the couch around 3 for like 30 mins. Is it possible I could still have my period but still also be pregnant, just really early in?? I took a test 6 dpo but was negative 👎🏻 thoughts?
