I think @MrBigsCat was saying she's impressed that you're having sex at 6 weeks weeks post partum, rather than having been through it herself.
Be gentle with yourself, take your time. I too can see a faint line but agree with pp, keep testing. It may not be what you want or planned for, but you can take a bit of time to think it all through. I don't know about your circumstances but in my experience people can be incredibly helpful and supportive and if you choose to go ahead, you may fast develop a superb support network to make it all feel manageable.
