What was your first Beta HCG result?

With DS1, I got a BFP at 8dpo but didn't get a blood test until I was 21dpo, when HCG was 6209.

For DS2, I only got a BFP at 13dpo (and I was POAS from 5dpo). HCG was 51 at 14dpo and 834 at 20dpo.

I was testing with FRERs. These were natural cycles

Hey, my results were all natural cycles (using OPKs) so I'm not sure if this helps. If you want to do some maths on the numbers though - here goes:

M/C 1: HCG 73 at 11 dpo (BFP on FRER at 8 dpo)

M/C 2: HCG 98 at 15 dpo (BFP on FRER at 9 dpo)

Current preg: HCG 21 at 10 dpo, 306 at 14 dpo, 8656 at 21 dpo (BFP on FRER at 9 dpo)

N2L I had a super feint BFP at 9dpo on FRER. But remember levels are different every time. I think I always faced facts a cycle was over if no line by 12dpo. Just checking you know of the website betabase.info? I think this is the best indicator of hcg levels at dp and you can segment by age if this might help. Fingers crossed it is still to come for you this cycle xxx

N2L I got my first BFP on a FRER at 9dp3dt, it was light but I didnt need to squint or anything, it was def there.

Best of luck xxx

Problem is that pregnancy tests detect regular hcg where as H-hcg is what we produce initally and this is not detected on hpt. However H-hcg is detected with blood tests.

Does that make sense?

ETA: I recall reading a study on hpts a few months ago and if I remember correctly some of the most sensitive tests are really bad at detecting H-hcg, but there are a couple of tests that have lower sensitivity that are much better at detecting H-hcg so can detect pregnancy earlier then the more "sensitive" tests.

I'm going to add mine so that anyone reading this later on can have them.

HCG 441 - at 14dp3dt Fresh = DD2
HCG 530 - at 14dp5dt FET = Blighted Ovum
HCG 701 - at 12dp5dt Fresh = Heartbeat so far

With the last results I got my first + HPT on a FRER at 5dp5dt. It was light but not so light you had to hold it just right with you toungue out standing on your head.
I got my first +HPT on a Lullaby Conceptions HPT at 4dp5dt. It wasn't a squinty one either although it was light.

Hi Ladies

Just thought I would chime in with DS at D35 post 1 x fresh 5 day transfer my HCG wass 476, I found out today im pregnant D35 post 1x frozen embryo transfer. Does this mean its twins?? Oh and I have very low progesterone despite 2500mg a day? Any thoughts gratefully received.

Bee - The only way to know if it's twins is to have a scan. Levels "could" indicate more than 1 but it can also just indicate 1 really strong singleton. Whatever you do don't google your levels. It will only drive you bonkers and it did me.

All my FB IVF mums and to some extent my clinic were indicating to me it was twins and so I had got my hopes right up expecting twins on my scan. I was really disapointed it wasn't. I'm angry at myself for even entertaining the idea of twins. So I learned my lesson on not to analize you levels too closely. Scans are more accurate.

Hope that helps. I don't want to burst your bubble. I just don't want you to go through what I have just been through.

Big congratulations on your BFP!

My first HCG with DS2 was at 20dpo (according to my FS, but according to my OPK was 17Dpo so not sure) was 1347., and progesterone was over 100, where as with DS1 HCG at 16 dpo was around 400, but progesterone was below 60, so diff results each time. Agree you shouldnt reflect on the numbers too much!!
