So, I had my "8 week" appointment this past Friday and based on when we think I got pregnant (99% sure about the date) I should be due around April 28. We saw our little stow-away in the ultrasound with the little heart fluttering away but size wise, the baby was measuring more at 6 weeks than 8 weeks. The estimated conception date based on 6 weeks puts conception 2 days before I took the HPT, and that thing went positive before I finished peeing on the stick. My OB suggested a progesterone test to make sure my body is trying to sustain the pregnancy even though I am still nursing my 14 m/o and therefore should be producing plenty of progesterone. We have another u/s scheduled for this Friday and I am seeing my acupuncturist tomorrow in the hopes that she will be able to bolster the pregnancy and my body. Has anyone else had a similar experience? Am I on the path to a miscarriage or terminating the pregnancy?

Its possible you built up hcg really quickly. What I want to know is what they mean by "conception"... the day you ovulated, or the day the baby implanted? U/S can be off measurement wise by quite a bit, but even a couple days would make sense if theyre talking about implantation... it doesn't take long for hcg to add up to measureable amounts once the baby implants. I could say it would go either way honestly, without knowing every detail, but a heartbeat is definitely a good thing to see

Those dating scans aren't infallible. Yet another reason I'm a fan of not peeking too much and letting the kid come when they come.



I wouldn't worry about it too much. Easier said than done, I know. None of us is in control in this journey, we just have to trust the universe that what is meant to happen will happen.

Sending lots of positive vibes!

If you back calculate from the May 16 due date that I don't believe then conception, not implantation, occurred on August 24 and I took the HPT on August 26.

Who knows, maybe I am just being obstinate about the conception/due date. I know no one is born before their time, and whether we like it or not, no one leaves before their time; if this pregnancy ends then obviously it's not time for #2 to be born. It's just good to hear other ideas and get a little support. The first thing my Mom said when I told her what was going on was "You know, a lot of women have miscarriages. What are you going to do if the pregnancy isn't healthy?" All things that I am thinking about, not real constructive at this point since we don't even know whats going on. Oh well...

Some possibilities:

Old U/S machine...? new/unexperienced tech that didnt measure good..? One little .5 cm off that early and it changes your date by a week

Tilted uterus and u/s measurement is hard to capture.??

OK it takes at least 5 days for hcg to get to a high enough level for the lowest detecting hpt to pick up (25mIU). So there is no way that you conceived just 2 days before taking it. U/S measurements are off by up to 2 weeks either way. I do not like u/s for dating for this reason. It causes stress for no good reason.

I had a u/s done because I didn't believe it
I'd taken a HPT and it came up neg. The date the u/s tech came up with is impossible. We made baby one of two weekends in March and the u/s date is nowhere close to relating to either. The measurements are just precedent. It's an average of what baby measures on a given week, but we know each baby is unique and not every baby is measured


Don't sweat it!

Had the follow-up u/s yesterday. No growth, no heart beat, nothing recognizable as an embryo. So, I'm giving my body a week to see if it expels the pregnancy on its own. If not I'll be looking at a D&C or drug induced miscarriage.
