serious question


so me and the hubby are ttc. well I'm only about 4 days past peak ovulation and I've been so nauseas. I started cramping (period isn't due for like 10 days) and I never cramp this early. well I go to wipe... there's brown. I DO NOT have an std. It doesn't smell. I know gross... but if it was you ya know you'd make sure it wasn't like death or something. so what could this be?! I am waiting on doc to call me back. But I'm nervous they'll say it's a super early miscarriage? I've had one before. just hoping someone has an answer so I'm not freaking out. Thank you
