When I took first pregnancy test its become negative but second positive now what can do?

It's possible that you may have experienced a chemical pregnancy. A chemical pregnancy occurs when a fertilized egg implants in the uterus, but the pregnancy does not progress and is lost. This can cause a positive pregnancy test result, but the levels of the pregnancy hormone (hCG) will not rise as expected and the pregnancy will eventually end.

It's also possible that the second test was a false positive. False positives can occur for various reasons, such as certain medications, medical conditions, or even an error in reading the test.

To confirm whether you are pregnant, it's important to see a healthcare provider. They can perform additional tests, such as a blood test to measure hCG levels, or an ultrasound to visualize the pregnancy and determine its viability.

In the meantime, it's important to take care of yourself both physically and emotionally. Getting enough rest, eating a healthy diet, and avoiding alcohol and tobacco are all important for your overall health. Talking to a trusted friend, family member, or healthcare provider about your experience can also be helpful.
