Weird early pregnancy symptom.

Ok I have never had this happen before I’ve had 5 babies. And 3 MC. Now but my last was 4/26. It started with this one. But mild tailbone pain. And here I am 3.5 wks later with even worse tailbone pain then the first time. It’s unbareable at times. No matter what I do. Sit stand lay down etc. I’m retesting I’m Friday to see if we conceived again immediately because lately it has felt like it.. tailbone pain, sore boobs, headaches, dizzy
