No Experience with a Miscarriage

Hi Ladies,

I took a test last Friday. And then two on Saturday. All were Super dark positive lines. I was so excited. I believe I ovulated January 14 through the 18th.

But today I have been cramping all day long , at one point a weird sharp pain that lasted for maybe 10 seconds and then light bleeding (not super dark or thick)almost like the second day of  a period. I have had a few blood clot like clumps but nothing too crazy.

I’m just wondering for anybody That has experience with this… What do you think? I didn’t really think anything of it until I got home and was sitting with my thoughts. So I will call my doctor tomorrow. But what should I ask for? A blood test? To test for hcg?
