Questions (TMI)!!

I had my second IUI today. The dr had to use a qtip to clear my EWCM away from the cervix opening. Did the IUI and sat with my butt in the air for 10 minutes. Now that I’m home I’m having discharge. The dr said after he put the sperm in nothing came back out. At all. Could this be sperm? I didn’t think so but questioning what I may know now or could it just be discharge from him being in there? Responses ASAP to make me feel better would be super! Thanks in advance!!
