pretty sure I'm losing this baby

Rebecca
I lost a baby a few months ago at 6w5d so I've been waiting to make it past that hump and then I figured everything would be fine! Well I'm 6w5d today and I just started bleeding and cramping 😢 what is wrong with me, why can't I keep a baby! I have two girls and both of their pregnancies were free of any complications! Now I've lost two in a row....I'm just so sad.
