You should absolutely test right away. A 30-day delay means you are potentially around 8 weeks pregnant, and you need to start your prenatal vitamins. Don't wait any longer, do the test tomorrow morning.
Definitely check immediately with a basic 50-rupee urine kit from the pharmacy. If it's positive, you'll need to plan your budget for the first doctor's visit, blood tests, and scans, so it's best to know early.
Yes, 30 days is a very long delay, so a home test will give you a very clear result. My mother always said to stay calm and check early in the morning. If it is positive, please book a doctor's appointment immediately for your first scan.
Arre, 30 days is a whole month, did you forget to check or were you just avoiding the reality, haha! Yes, go do it right now, the HCG levels will be super high so you will get a dark line instantly.
