you werent pregenant
yes
did you bleed? if not then it's just fine.
It depends on your period. Usually pregnancy tests pick up a pregnancy by 4-5 weeks. So if you didn't get a positive last week, you are probably between 4-7 weeks :)
you could be but most likely not. pregnancy symptoms are so common and sometimes mock pre menstrual symptoms (pms). you should get a positive result on a pregnancy test by now if you are.
Yes, you should take a pregnancy test.
No. It just means that the pregnancy hormones that were making the symptoms stronger are now decreasing which is what is meant to happen during pregnancy
Take a pregnancy test
It is possible that if you had preg symptoms and now they have gone that you have miscarried. This is usually the case, but it is possible that you are still pregnant. There are quite a few pregnancies (more than you would expect) that are twins and one twin dies. The second baby is carried to full term with no problems. If you are carrying twins you will have worse pregnancy symptoms. It is possible that as the one dies, some of your symptoms seem to disappear as the body settles to a singular pregnancy. Any miscarriage must have bleeding to rid the body of the pregnancy - did you have something like a period? It would probably look like a heavy period at 5 weeks. Cramping is usual, but not always. You are best to go to the doctor and have an ultrasound. They will have a look and tell you if the baby is still there. If the baby has gone, and you haven't bled, you will probably need a D&C. This will scrape out the remains of the pregnancy. If this is not done it is possible that the body will continue to "support" the pregnancy when there is no baby. Yes, that is possible that you have miscarried, but it could just mean that your body is handling (or you may be adjusting) to pregnancy symptoms. But five weeks is a little early to lose pregnant symptoms. If you are early enough along, your body will dispose of the fertilized egg and you will probably never know. Good luck to you.
It can be normal to bleed during the early parts of pregnancy but not blood clots. I suggest you go to your doctor asap and tell them whats going on.
usually you need to wait about 6 weeks after.
If you are getting other pregnancy symptoms, yes, take another test.
they count the two weeks before you concieved when calculating how far along you are, so really it should be from the first day of your last period to now, that will tell you how far along you are! :)
