On my second pack of birth control pills, stopped taking placebo pills of first pack 4 days in. Started a new pack on day 3 of period, am I protected?

Probably. I cannot tell exactly from your question, but as long as you did not go more than 7 days between the last active hormone pill of the first pack and the first active pill of the second pack, then you should be covered. You don't need to swallow the placebo pills, but they help you stay on time with the routine.

Is it normal to not have a period on Depo shot? Got first shot in the middle of my pack of birth control pills, finished pack now no period on placebo?

Yes. When you get a Depo Provera (medroxyprogesterone) shot in the middle of a birth control pill pack, it is very likely that you will get a delayed period or no period at all. To be safe you may do a pregnancy test. After it is negative, as long as you take your future injections of Depo Provera (medroxyprogesterone) on time, you will be protected and it is normal to not have any menses during the time.
