My periods are getting late from past 8-9 months. But this time they are about 45 days late ehich means i have missed a month. I took a pregnancy test after 25 days of missing my period and that was negative. And i have no other sign of pregnancy like nausea, sensitive breasts, back ache or bladder issues. What should i do? And can i still be pregnant? How many test should i take to be sure. Please answer fast.
