Any suggestions?!?

I had my AF last week and just finished my Clomid 50mg. At the same time I am still taking Amoxicillin from a cold. Just today I started noticing a faint red tint in my cm.

I was taking Clomid 50mg also last month and tested a BFN a few times then had my AF. I am just worried what is that red tint in my cm. I am seeing my OBGYN tomorrow. I just want know if anybody went through this.
