No. This is just an artery in your neck that you can feel your pulse in.
Of course not. Rather than relying on sayings you should get tested if you suspect you could be pregnant.
It's your own pulse/heartbeats. if you think it's the fetus' it is not. You can never feel the heartbeat of the baby.
You could see a heartbeat if they do a transvaginal ultrasound.
no. they have their own heartbeat. if you are pregnant and go to the doctor they can put a fetal monitor on you and you will be able to hear the babys heartbeat.
Yes, definitely! That is a sure-fire pregnancy test!
not usually
yes.
Yes it is your own.
Depends on what species the question is about.
Three weeks pregnant is a week before you miss a period so it is impossible to know it is twins. If you are three weeks after conception, (5 weeks pregnant)it is still early to see a heartbeat.
well it really depends if its 1. ur heart. but if i were u i would take a pengnecy test just in case
Then you are going to have a miscairrage.
