Has this happened to anyone else

Your super pregnant. Congratulations

High HcG does not correlate to having twins. At around 6 weeks, you would have high HcG so more than likely you would have a dye stealer test.Congrats!

How dark the line is does not always follow how many babies are in there. With my twins I didnt even get my positive until 16dpo and it was super faint. My hcg levels were in the normal range at 5 weeks 5 days. Absolutely no inkling whatsoever that I was having twins until the ultrasound at 11 weeks. (These were babies 4&5) i had a stronger test with my most recent singleton pregnancy at 16dpo than I did with my twin pregnancy.

Not nessary, I had dye stealers when expecting my lil one and it was only her, guess it just depends on your hcg levels some rise faster than others.... But you never know 😁
