Hi everyone, did anyone else experience low HCG levels in early pregnancy? Also an empty sac at 6 weeks? I had some light cramping and a headache with blurred vision so my doctor sent me in to be checked. My HCG was 627 on Tuesday and came back to 2209 today. The doctor said it was low for being 6 weeks and the fact that the sac was empty was more concerning. I don’t think I’m 6 weeks yet I ovulated late ( I think ) just looking for some advice/input/stories. Thank you!
