Is it normal to have pink spotting the day after a transvaginal ultrasound?

Ky 8-15-17👼🏼 & 10-28-17👼🏼 Pregnant with my🌈💕

I had my first ultrasound yesterday at 6 weeks 3 days and was measuring at 6 weeks 1 day. Ever since then it's been sore inside especially when I put my progesterone suppositories in. All day today I had a pinching sharp pain that felt like it was in/on my cervix all throughout the day today. And I called the nurse and asked if that was normal and she said it could have maybe been from the ultrasound or my suppositories irritating my cervix causing that pain. But it hasn't started until today, the day after my ultrasound. I just went to put my progesterone suppository in for the evening and when I took the applicator out it had pink discharge all in it. Could this be from the ultrasound I had yesterday??? Is this normal? I haven't had any pink discharge on the applicators until now. Also a few hours after my ultrasound yesterday that lubricant stuff that they put on the wand, came gushing out of me filled with brownish tan discharge. Is this all normal??
