Yeast infection or vaginal progesterone??

I take progesterone vaginally every night and I did notice that it leaks out the next day (some days more than others). But the last day or so I’ve felt like maybe I’m getting a yeast infection. Slightly itchy from time to time, and discharge yesterday was white (which I’m pretty sure was partly due to the progesterone), but today i noticed like a very slight brown clumpy discharge. It’s like tiny clumps, and only 1-2 when I wipe. I read that could be yeast infection too. Of course can’t call doctor until Monday. What do you think?? Is a yeast infection harmful to baby? I’m just over 6 weeks and had an u/s yesterday with a good heartbeat.
