Help think we're miscarrying

Tanara • With the love of my life ❤️ Mommy to four; twelve, nine, four & two!
So two days ago I look a test and got a positive after 5 months of trying. 
Yesterday I was spotting so I took another test. (Top is from yesterday) 
Then this morning I took another one as the bleeding has stopped and I got a very faint positive. 
I'm going to buy one more test and see if I get the same faint line. I am at a loss of what to do. If I am miscarrying this would be the second time in a row. Thanks for reading. All opinions are appreciated
