if it was Performed Properly .. with the needed precautions ... it DON'T
haha, for sure, this is imposibble!!
Yes
You really need to talk to your doctor or the person who did the ultrasound about this.
If it was a vaginal ultrasound then yes it could give you some spotting.
You could but keep in mind that it could also very much change depending on how the baby is measuring at the midway ultrasound. Even then the due dates are just estimates!
this could be normal. it can take up to 6 or 8 weeks for a fetal heartbeat to show up with a vaginal ultrasound.
I understand what you are saying when you say messuring, they messure the sac and it calculates what the size is to get the age of the sac/fetus.
You could see a heartbeat if they do a transvaginal ultrasound.
You should have an ultrasound done if you believe you may be pregnant with twins, at seven weeks the uterus is behind your pelvic bone, not yet visible except by trans-vaginal scan.
Ultrasound machines are quite pricey, but you could definitely find one online. For a good place to start, see: http://www.absolutemed.com/Ultrasound-Machines
Yes.
Alum can be used to tighten vaginal walls (the internal vaginal canal). There are products on the market specifically for this. Therefore, in theory, alum could be used to shrink the outer labia (lips) of the vagina. However, this "virginal muscle" assuming you mean the hymen, is something of a misnomer. Prior to sexual intercourse, some females have a hymen in place, some don't. The hymen is very fragile. It can be lost painlessly, especially if tampons are used during menstruation, or if the female has an active lifestyle, or participates in sport. The absence of a hymen at the vaginal entrance, is not an indicator of lost virginity. Bringing God into what may be an already tense, anxious situation, helps nobody.
