TTC#2

We’ve been trying since December to have baby #2. The other day I took a test and the line was SO faint I was told it wasn’t positive. Today, much earlier, I had a very small amount of brown discharge and small amount of blood. Started to get very sad. Well then I came home and took another test!! It was more of a line but VERY thin line... then tonight I have more blood. Still a small amount, more than earlier but less than a period. What could all this be!! Could I be pregnant or another month of no baby??
