Tried my breast pump at 16 weeks.......

Okay, super weird but I tried my breast pump today just to see what it was going to feel like or how it was(FTM)...anyway, I noticed some clear, sticky substance quickly after so I stopped and googled it to find out what it was. While I was reading about the fluid it said that it could cause preterm labor. I only tried it for maybe 10 pumps but I’m nervous that I screwed up. Please tell me that little bit won’t effect my pregnancy and make me go into labor early...
