Practice breathing exercises.

Thanks for your quick response. Today i did tests with pregnancy kit and they came to be positive. what should be my next steps?

Hi. Having delayed period is not always the only sign of being pregnant. Sometimes stress levels or hormonal fluctuations can also delay your cycle. Have you always had regular periods? If not then, you can wait. If yes, are you experiencing some other symptoms of early pregnancy? Like nausea, tiredness, vomiting? If you are experiencing a white discharge, back pain, heaviness in vagina, you can wait for your periods to come in a few days. Quick tip - you can always get a UPT (urine pregnancy test) done to be reassured.

you will get accurate pregnancy test only after 45 days ,so please wait for 10 more days n can check it in a pregnancy kid from med store
