18 weeks pregnant and bleeding...

Hey everyone,

So I’m 18 weeks pregnant and on Monday I started bleeding. There was no impact or any event that lead up to it. It was really scary so my partner and I went to the ER. They did an ultrasound and baby’s heartbeat looks good but they didn’t give me any information on why I was bleeding. It has not stopped, it’s getting a little less heavy but it has been three days now... I can’t see my OBGYN until tomorrow and to tell the truth I’m freaking out. I’m trying really hard to stay calm as I know stress won’t help the situation. Please if anyone has experienced anything similar, let me know. I’m feeling a little depressed because I feel like this is my fault. I just want my little princess to be ok. Any advice is welcomed!💕
