Possibility of twins?

I took letrozole this month and baby danced naturally. I got a faint positive at 8dpo and then got a strong positive at 12dpo today. Period isn't due for a week. I've been pregnant (and miscarried twice before this) and have never got dark tests so early. Could this be a possibility of twins?
