Need some answers! 🙏🏼

I am 5 weeks and 3 days postpartum. My husband and I had sex 3 times (no birth control) (just pulled out) I took a hpt this morning and got a super faint line do you guys think it’s from my previous pregnancy or a new one!?

& pleaseeee don’t comment that I shouldn’t be having sex etc. That’s not what I’m asking.

Thanks in advance! ❤️
