Hello dear Your symptoms could be a pregnancy. But it should be confirmed by pregnancy kit and or blood HCG test. Pregnancy kit will give positive result 8-10 days after delayed period. So go for above tests to accurate confirmation of pregnancy. If above tests will come negative then other cause of delayed period like hormonal imbalance, ovarian cyst, endometriosis and thyroid dysfunction should rule out by consulting the gynaecologist. Period is induced by progesterone pill in absence of pregnancy. Avoid stress, take healthy diet and drink lots of water. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
