Implantation dip while on progesterone?

Would you still get an implantation dip while on progesterone suppositories?? Is charting effective while on progesterone? Can you be pregnant and NOT have an implantation dip in temps??

Thanks! I am really curious how Progesterone supplements effects your bbt. This is my first month charting and I think its going to take me awhile to get the hang of it!!!
