8 weeks but scan only 6 weeks :(

oh my exact scenario. was supposed to be 6-7weeks but when I went for the first check it was too small to look like 6-7. So they got me back 2 weeks later to do another scan to check on the dating and if baby was viable so by right baby was supposed to be 8 weeks for the later scan but when they measured baby, it was only abt 6 weeks. I supposed the ovulation was late cuz I tested myself if I was pregnant on the day I was supposed to have my period, it was negative. then after few days, my period still didn't come so I tested again and I was positive this time. but yea just glad that everything is fine for now. I'm still doing a dating check next week though to make sure it's on track *cross fingers*

Same! During first visit, by calculation of last period should be at week 6, but on the scan it’s jus too small. So 2 weeks later I went back and scan again using transvaginal ultra sound (thinking it should be week 8 already) and it measured week 6 instead, so most likely the conception date and last period had some difference and we calculated 2 weeks more. So now we restart and base at week 6, in another 2 weeks will check again and see if it’s progressing normally.

Based on the first day of my last period, I should be 8 weeks. But when I go for my first gynae appt at “8 weeks”, the ultrasound measured only 6 weeks. During my 2nd appt, supposedly 8 weeks based on first ultrasound, it then measured 9 weeks during the 2nd ultrasound. I asked my gynae and she explained that sometimes the ultrasound can’t measure accurate size while it’s still small, so usually need a few appts before can really tell the exact week you’re in.

For me, my period had been very irregular. My last period was in end July. I tested early October and the positive line was faint (due to being very early in gestation). After a few scans within a period of 2 months, from the size and growth progression, baby was estimated to be conceived in September, not July or even August. I guess last day of period may not necessarily mean the start of gestational period.

I had the same experience. thought to be in week 7, ended up at week 5. Most prob due to my period cycle, becos on n off will delay few days. hence ovulation cycle is delayed too. I also had a transvaginal ultrasound cos it's too small. After 2 weeks, I went back again for abdominal scan and can hear his/her heartbeat

I was supposed to be about 7 weeks but gynae did transvaginal ultrasound and measured saying I should be about 6 weeks instead and she scheduled me to go back after 4 weeks time for another scan. So I guess it's ok? And I also I was able to hear the heartbeat so amazing! So don't worry so much ya!

I had my first check at 8 weeks assuming that I was 10 weeks into my pregnancy. Gynae say it is probably the result of my irregular period. Don’t worry! Head back for your check in 2 weeks and you’ll likely hear baby’s heartbeat by then! :)
