Sorry to hear that. But for your reference, fetus can be detected by ultrasound as early as 4th week. (more difficult than later in the pregnancy of coz due to the small size). From a medical pt of view, many women lose their fetus without realizing they were pregnant in the first place (b/c of developmental defect, or maternal environment unsuitable). At least you found out about this one that you are having, and can do sth about it.

Baby needs at least 20 weeks for any realistic chance of survival. The doc is right, there's nothing you can do to help the baby at this stage.
As for surgery ruining ur chance of future preganancies, that depends on what kinda surgery la. In your case, just have to take out the cyst. If the wound does not heal properly, and forms scar tissue, it may block ur follopian tube (also depends on where in the uterus ur cyst is). But there are ways to correct that too. Don't worry too much at this stage. Your doc probably will tell u the risk involved when u have the surgery.

remember morning sickness varies in diff ppl. some women have it during their entire gestation period, while some only have it at the early stage. So maybe u are just over that morning sickness period?
