Rainbow Baby

So I took a frer on Friday and it had just a vvvvvvvf beginning of a line. I didn't get my hopes up. Then yesterday I wiped after I peed and had some reddish brown blood and thought well I'm out. (AF is due Wed) So I thought she was just early to crush my dreams again. Well I had 2 more frer tests and thought to take one with my 2nd mu and I waited and then I look over, and there's a faint 2nd line!! It barely catches on camera so I can't post a pic just yet but I didn't get a BFP until 3 days after missed AF before I miscarried last Oct. Prayers this rainbow baby sticks around!!

Also, is it normal to have a spot of reddish brown blood a couple days before AF and still have a healthy pregnancy?
