Progesterone suppository color?

Chrissy
Hi- anyone out there using progesterone suppositories, just wondering what color yours are?  I've been on them since July for <a href="https://glowing.com/glow-fertility-program">IVF</a> and supposed to continue until 9-10 weeks.  My initial bottle was pale yellow pills.  I just refilled at a different pharmacy and the ones they gave me are a red-brown color.  
Just wondering if anyone has used the red brown ones and if they are also ok. 
I much prefer the yellow ones!  Being a suppository, of course they cause discharge. And red discharge is unnerving to a pregnant woman, even when it's obviously the medicine  😳
