Hi guys, I am 17 weeks along with my second baby. I had bleeding at 8 weeks and have had much more extreme symptoms with this pregnancy. I was thinking twins at first but I had a 13 week ultrasound where there was no mention of another baby (but I never mentioned I thought there might be two either) so I tried to shut out the thought of 2. My question is that I bought a doppler and have consistantly been hearing 2 heartbeats. They are always very similar in rate but seem to be getting farther apart. I know it is not uncommon to hear 2 with a singleton and I was just wondering if its common to hear two heartbeats EVERY TIME with a singleton or if my original thought of twins might be right and was missed on the ultrasound. Any thoughts would be appreciated!

You may be hearing your own. If you had 2 you would have found out at the ultrasound. Good luck.

Definately not my own, I can also hear my own very easily at 60-80 bpm and two more from 140-150bpm.

It would be really tough to miss twins at 13 weeks. You're probably hearing an echo of the h/b or your pulse in once of your internal organs.

My DR never did the doppler with my twins because she wouldn't know what she was picking up and she wanted to make sure she heard them both. You get a ton of echoes, pulses and beats all over. If you had an u/s at 13 weeks they should have seen something.

it is VERY common to hear two in a singleton pg. The placenta and umbilical cord both have a pulse and the veins that feed the uterus with blood also will pick up as a hb. 99% of the time when 2 are heard it is one baby. Amniotic fluid is also highly conductive so you can hear two hb (even at different rates) in different places via doppler. Unless two dopplers are used at the same time it is difficult to know if you truly are hearing two or just an echo or a pulse from the above mentioned. A 13 week u/s should pick up an extra limb, sac, umbilical cord....something as babies that big can not shadow each other all the time.
