No I doubt it can miss it that late.
It is absolutely impossible not to see SOMETHING on an ultrasound at 3 months pregnant. Pregnancies are most commonly confirmed without question at around 8 weeks pregnant. So, given the ultrasound is done by a qualified technician, there is no way you could miss a pregnancy that is 3 months along.
If you miss your period there are hundreds of reasons why you could have missed it. Pregnancy is just one of the many.
Yes it can
Most women miss there first months period after becoming pregnant. Some have their period throughout pregnancy.
The first trimester of a pregnancy lasts up until week 12. If you are 11 weeks pregnant and you have a competent sonographer, there is NO WAY you could miss seeing an intrauterine pregnancy (a normal pregnancy inside the uterus). If you had an ultrasound and the sonographer didn't see anything (even as early as 5 or 6 weeks you should see a gestational sac) then you have probably miscarried already. Take another pregnancy test with your doctor's guidance. Another scenario that might come up (if your pregnancy test is still positive) is that you might have an ectopic pregnancy (where the egg implanted OUTSIDE of the uterus). This is fairly common but can be a serious disorder. The egg can implant anywhere in the pelvis or abdomen, but if you're 11 weeks along and you're not in a lot of pain, then that's probably unlikely. Go back and talk to your doctor.
When you miss a period and take a pregnancy test.
Pregnant women usually will first realize they are pregnant when they miss their period. Other symptoms include tenderness in the breasts and morning sickness.
After you miss your period.

No the ultrasound is usually right, it's called a miss miscarriage I think.
Most fertility experts will tell you that you won't have any pregnancy signs or symptoms until the embryo implants in the uterus. This can happen about the time you miss your period but for most women, pregnancy signs & symptoms will not kick in noticeably until you are 6 weeks pregnant (about 2 weeks after you miss your period). Some women don't have any pregnancy signs or symptoms except for a missed period! Anecdotally, many women who have posted on the internet & have discussed pregnancy signs & symptoms will tell you that they knew right away or a few days before their periods were due. If you are very in tune with your body, you may notice small changes right away. However, remember, most of the early pregnancy signs & symptoms are very similar to premenstrual symptoms and it is often difficult to know the difference until you miss a period.
Yes, although you could just be ovulating because many women spot when they are ovulating. If you miss your next period, take a test
