Hi dear, i dont think bhcg numbers really mean much on its own. You will need two sets of numbers 48hrs apart to read anything meaningful. Have seen sisters here with even higher numbers on BT day like 2000+. They went on to have normal pregnancies.
For me, I was twice mistakenly diagnosed with ectopic pregnancy becos my bhcg was btwn 1500-2000+ and the docs couldn't find the sac. I also went in to O&G with bad cramps so the docs immediately suggested it could be ectopic and wanted me to do D&C the very night. I pushed for more detailed scans at KKH imaging and diagnostic centre. To me, even if docs didn't manage to find the sac in my womb, i need to know it's really located outside of womb like in the fallopian tube etc. And both times, they managed to locate the sac during the detailed scan though it took more than an hour as I was told I have a high riding cervix hence the difficulty in visualising during early pregnancy.
I was also asked to retake my bhcg levels and the numbers were doubling as it shd. Jts.
However, if u r having spotting and experiencing persistent cramps on one side of your abdomen, pls go to O&G to chk it out. Pain in shoulder is also a tell tale indication of ectopic.
All the best and take care!
