Could it be???

So my hubby and i are trying for baby #2. Yay!! And this month we are hoping is it. Then the monthly visit comes (Tuesday) and i had a little spotting. Negative test. I’ve been having all signs of it, tummy ache. Sense of smell. Irritability. Metal mouth. but nothing yet. Could it be too early to test and get a positive?? Or do you think it’ll be another month??
