helppppppp!!!!!!!

I've been on the low dose birth control of 20mcg called alesse 28, I'm on the 7th pack and my period isn't regular as this month I got it during the second week of the active pills, I know it is causing me to bleed more and have spotting but I have some questions, 1 will I still get a period during the sugar pill week? 2 is the pill protecting me against pregnancy regardless? 3 can a girl get pregnant if the guy touches her (With most likely no precum on fingers)? I was fingered by my guy and he said his hands where clear but it was dark and he aeemed dry but I can't say for sure! Three days after that I started spotting which now got heavier
