Actually, yes! Day 31 is perfect since it's past the usual cycle. Try to do it tomorrow morning. Also, make sure you don't do any strenuous workouts or heavy yoga until you get the result and discuss with your doctor.
Haan, 31st day pe to test bilkul kar sakte hain na. Ek-do din upar hi ho gaye hain. Kal subah test kar ke dekh lo, clear lines mil jayengi agar positive hai toh.
Arey haan, bilkul kar sakti ho check! Missed period ke baad toh result ekdum sahi aata hai. Subah-subah sabse pehle urine se test karna, bhagwan sab accha karenge.
Beta, 31st day is a very good time to check because your periods are missed now. Do the test calmly in the morning. Drink lukewarm water and avoid lifting heavy things ghar pe until the results are clear.
If you have regular 28-day cycles, day 31 is great to test. But with my PCOS history, my cycles were longer, so I had to wait till day 35 or 40. If it comes negative now but period doesn't start, try testing again after a few days.
