Faint line or I'm seeing things?

I've been TTC with my husband for a year and a half. I never had problems conceiving, I had 3 kids already from a previous marriage, he has none. Never was able to procreate before but he has never visited a doctor either. My period was 5 days late and like every month I got a pregnancy test from a drug store, it came out negative so I threw it away. Not even 5 mins later my husband went to take the trash out and he saw it and said omg why were you hiding this from me? I said,it's only 1 line. But when he showed to me it had 2. A faint line. Could it be possible?
