I got my BFP on 2/14. My periods are super irregular so my DR had me go get blood work done. On 2/16 my hcg level was only 323. I went and retested yesterday 2/27 and my hcg level was 13,000. Is that a normal progression? I know it's supposed to double but I feel like it jumped a lot. I go in for my first ultrasound 3/7 so I don't really know how far a long I am at this point.
