Could this be the month?

Disclaimer: I know it is way too early for real pregnancy symptoms and testing. I just wanted to know if anyone had these symptoms, pregnant or not.

So far I been TTC for 6 months, but this month I have started seriously tracking everything ( BBT,CM,Cp) to try to conceive this month. I have a 29 day cycle on average. I swear I ovulated this month on CD 11/ 12 ( Cp and Cm were at its best)and BD on CD 11.

Now I am about 5-6dpo, and I started having different symptoms than my regular cycles since 3dpo such as:

Low abdominal bloating and twinges

Breast darkening and twinges

Extremely tired for no reason

Hot flashes ( even in a well A/C area)

Now I know these are similar to AF symptoms, but they came a full week earlier than they usually do ( AF should be coming around 4/15/18)! Is this Af or did I possibly conceive earlier than usual?
