Bilighted Ovum

So I think I’m having a bilighted ovum due to having an empty sac on my previous ultrasound. I go in tomorrow for another one. My question is what type of discharge did you have when you started to miscarry? I ask cause I’ve been having this pinkish stringy discharge and I’m wondering if I’m starting to miscarry now. I would really appreciate if anyone who has experience it would help me out. Thank you
