Could a small amount of liquid that fell out of my mouth on my phone interfere with the effectiveness of my contraception?

Hi, today I had quite strange situations. I took a birth control pill at 7:40 p.m. and about 11 p.m. on my stomach above the phone with an open mouth, and at one point some liquid from my mouth ordered me to call. These were fine colorless and 1000 droplets. So I found that it's just slina, but now I'm starting to worry that it might be water that i was odbila and I did not feel it? I did not feel bad, nor did I have problems with my intestines. Vomiting also did not occur, or is the protection then maintained? Besides, it was already 3 hours 40 minutes after taking the drug so it should probably already be at this time wchlonac? I have one more question. Due to the fact that once I had to take an extra tablet I start a new blister on Friday, but I do not hide that it would be more convenient for me to start it on Thursdays, because for the weekend I often do not have at home. Can I cut the placebo tablets in this situation, take them 3 instead of 4, and start the pack on Thursday? Takes vines.
