Orange blood?

So I took plan b last Tuesday and I am on my period now. (I think and hope.) I also have a UTI and have taken my first days worth of the medication they gave me. When I just went to the bathroom I noticed that the blood was orange.. is this a side effect from the UTI or the Pill? Also I've been seeing a lot of little red specs when I wipe. Is that blood from the UTI? My period had not been a "normal" period for me this time, which I knew it wouldn't be, but this stuff is just weird. I also used a miconazole treatment last night because I thought that I might have a yeast infection. Could that be anything?
