Flu like body aches

Career mom

I have been ttc for the past 5 months. For my 3rd child. This month I was on otc herbal fertility drug, bbt and ovulation test. I am 7 dpo now since yesterday I have had pelvic pain similar to lightning crotch and my whole body just aches like I have the flue but I don’t. My bbt is still elevated also. Could these be early pregnancy signs?
