disappointed :(

so I have a 6 month old and recently had a pregnancy scare, well I guess there's still a chance I could be, I'm on the pill but had unprotected sex before getting on the pill.. I've been taking tests and I honestly get disappointed when I'm not pregnant.. I mean it wouldn't be a bad thing if I was.. Now that I keep getting the negative tests it's almost like I just wanna have another baby do they are close in age. I only want two kids anyway.. But i don't think my husband would go for it. I kinda just wanna stop the pills and see what happens but I'm terrified to even mention that to my hub because I'm pretty sure he will say it's the wrong time. thoughts?
