Home pregnancy kits may help you establish your pregnancy, but other tests and screening methods are performed  to establish and confirm your pregnancy. 

Here are some of the tests and screening methods that are done during First Trimester :

1. Physical examination and other medical information: Detailed history and a thorough physical examination will also be performed to see if you have a healthy pregnancy and there are no complications or birth defects.

2. Urine and blood tests: Urine and blood tests will be done to check your general well-being and also to know about any probable signs of complications.

3. Ultrasound: An ultrasound scan is done. It makes the detection of pregnancy and also the detection of any problems related to pregnancy very easy.

With the above-mentioned ways, the doctor will not only be able to confirm your pregnancy but will also let you know about any complications that you may face during your pregnancy.
