All I want is another baby

Okay so i got a 6 month old little girl who I love with all my heart, and my husband and i want another baby so badly. But unfortunately no BFP yet and i been so stressed about it. Not to mention my body likes playing mind games with me making me think I finally did it but nope nothing yet. And not only that I bled for 2 days and it was super light, and I haven't been feeling myself but honestly I am scared to test because I always get my hopes up and the way i have been feeling I really might just cry this time..
