Hi, I just had an ultrasound at 2 weeks and 4 days after embryo transfer (5day blastocyst). The doctor didnt see anything. My first beta was very low at 57.6 (1w4d after ET) and then went up to 175.3 (2w1d after ET). Is it too early to see a sac using transvaginal ultrasound (Sep 23 was transfer day and today Oct 11 was the u/s). thanks.
Hi, actually your can see the sac only when Chat Doctor level reaches 1500. Also, Chat Doctor level should double in 48 hours.  If it is not happening, it indicates towards a failing pregnancy.  So, I think you should repeat a Chat Doctor test after 48 hours, and then you can be sure of the pregnancy.  Hope I have answered your question. Regards Chat Doctor.
