Mrs N
My af is 4 day late. Today is fifth day. I am feeling many pregnency symptoms like bloating, dizziness,fatigue, my teeth are getting sensitive, heavy breasts and painful nipples. I tested at home yesterday but my urine pregnency test is still negative with a very faint line or may b an evap. I am tired of testing and feeling these symptoms and not getting any result. I dont know why but since last 15 days i am feeling confident that i am pregnent. I dont what to do. Is this happens to others too?.. am i pregnent.? Any other felt like that and confirm pregnency afters? Pls respond and help me. I want to know what is happening with me.
