recommendations anyone???

Last week from Friday and Saturday I had forgotten to take my BC pills, I ended up taking them Sunday as my doctor had recommended. I forgot to take sundays and Monday's on Monday and ended up taking them Tuesday morning, and Tuesday's later that day. I am about 2 days late on my period now and I think I may be pregnant. Today I bought plan b just in case maybe it could somehow help, me and my boyfriend are not in the best situation right now to have a child. I wanted to see in case plan b doesn't work if any of you have suggestions on something I can take that would cause a natural miscarriage.....
