Can I test on day 30?

Should be able to see a line at this point. There are ladies who will test as early as 8 dpo (about 6 days before period) and get a very faint line. But it all depends on your body, how soon the embryo implants and how fast your body generates HCG for pregnancy test to detect. But if you are afraid of disappointment, i’ll wait till i miss my period before taking a pregnancy test. Good luck!

i hv at regular intervals... i test +ve a couple of days after missing

Can try the early detection from clear blue.
