I had sex on the 26th; no protection what's so ever. He didn't pull out, I didn't take my pill in three days and not on time the other days I did. My period was scheduled for the 4th, I'm two days late which has never happened since being on BC. I took a test, showed negative. Is it too early to tell? If anything I'm a little nauseous here and there but I think it's in my head.
