Spotting when inserting progesterone

Hi! I’m 10 weeks 4 days. I’ve had two normal ultrasounds, one at 7 weeks 1 day, and one at 9 weeks 5 days. I haven’t had any spotting until last night. I was putting in my progesterone and I noticed I had some blood on my finger (sorry tmi). I then had some spotting on the toilet paper when I wiped (pics below). I have had nothing since, and no spotting all day today. Has this happened to anyone else? Would you be worried? I know dr. has told me everything is much more sensitive so it’s very easy to bleed, but of course I’m very nervous. Putting in call tomorrow AM but wanted to see what you all thought in the meantime!
