Post Transfer Symptoms

hey y’all - does anyone know if any symptoms experienced post embryo transfer are a potential legit sign of pregnancy? I have achy ovaries, sore lower back, sore boobs... and they’re actually bigger over the last day or two. However I’m on Endometrin and estrogen pills and know these symptoms are also side effects of the meds. Assuming this is why they say ignore everything until your beta! Just wondering what y’all did and what your experiences were!
