Bleeding

Sarah • Married 5/31/14 Started trying for a baby 5/31/15 Chemical pregnancy 6/23/15 Pregnant again due 3/29/16
I'm 4 weeks 1 day today and just got cramping and a little bit of bleeding. Not as bad as a period but I'm worried it's a chemical pregnancy due to my hcg levels being 13 on Friday and 16 on Sunday. Had more blood work today and will see what it looks like tomorrow.
