Faint positive started light spotting at work.

Kylie • Rainbow baby girl December2018! 🤰🏼🌈

I got a faint positive Friday, yesterday I worked a 10hr shift and done some lifting and started sorta spotting. I've had 2 miscarriages and so far it's a light pink and mainly when I wipe. so far no clots or cramping, I'm praying that this isn't AF & that this baby will stick. any suggestions as what to do or why I might be bleeding
