paranoid!

My boyfriend and I are pretty sexually actively, I'm on birth control and he pulls out, I take my birth control on time every single day. But we didn't use a condoma bout a week or two ago and last week I spotted for a couple days and I concluded it was normal bc spotting after hearing different girls with similar problems on this bc but I noticed I was spotting again this morning and got nervous? Help? I'm on the generic brand of seasonale If that helps!
