So I went to the er

Melody

Last night I went to the er with some light spotting I was thinking I was at 5 weeks and 2 days they told me I was only 4 weeks and couldn’t see the baby they also told me my HCG levels were at 31 is that normal for being 4 weeks they didn’t think I was having a miscarriage I just want to know if anyone else at 4 weeks got hcg levels at 31 I feel that’s a little low any one else?
