HCG levels 18dpo / 5 weeks 3 days

[sandpiper22]

Yesterday my hcg levels at 18dpo or 5 weeks 3 days was 663. I’m going to check it’s doubling tomorrow but can’t help but think this is really low. I’ve had two losses before so this pregnancy = anxiety. Has anyone else had level like this at 5 weeks ?

@sandpiper22 Hi! 18 dpo actually corresponds to 4 weeks 4 days I don’t think your hcg is weirdly low actually. Mine was 140 at 14dpo, assuming it doubled every 48h, I’d have less than 600 at 18 DPO. And at 23 DPO I was at 5000. So if yours doubles every 48h, you’ll be past 5000 at 24 dpo.

My pregnancy so far has been smooth and I am at 19 weeks

Also, according to the beta base, you’re well into average for 18 dpo http://www.betabase.info/chart/basic/single

@kaykay I have PCOS so my periods are irregular, from dating from my last period it’s 5 weeks but it’s very confusing
Thanks for your story, I hope mine does the same. Anxiously waiting to that hospital appointment tomorrow seconds feel like hours

@sandpiper22 So when your period is not regular, you can count 2 weeks + days post ovulation. Because if you were to compare your hcg with people at 5 weeks + 3 days, your will indeed be lower, but that does not account for when ovulation and implantation occurs. At your first ultrasound your baby might also be smaller than expected counting from LMP, so try not to worry about that!
