After TRYING to go to the bathroom last night I couldn't. But I had to wipe Bc I had what looked like ewcm but tinged brown. I have my first ultrasound and dr appt tomorrow so we can check on Beebe. But I'm kinda scared. This never happened I'm my last 3 pregnancys. And why's it brown?! Any advice or anything would be great. Thanks.
