For there to be viable semen (on somebody's hand, freshly ejaculated) would you have to have enough that it is visible for it to be viable?
Also, I just finished up my first month on the combination birth control pill. The latest i've been with taking it was an hour and a half late. Otherwise I've taken it everyday at 10 (except for the last 2 days I took them at 9 15 and 9 45). If I took my placebo pills and took my first active pill again yesterday at my usual time (10PM), am I fully protected? Am I fully protected even the last day of my placebo week?
Yes, your hands would have to be visibly covered in semen and then rubbed onto a vulva for it to be a viable risk.
As per your other questions; yep, you're still at full protection in the placebo week. With the combined pill, the pills have to be taken within an 12 hour window; with the minipill, it's a three hour window. So, a window of an an hour and a half is fine, and it's safe to take them a little early like 9ish onwards, too. As long as you stay within 12 hours of 10 if it's the combined pill or 3 hours of 10 if it's the minipill you take.
