hi, i did a blood test july 3rd and it came out positive. repeated it again 22nd july, august 6th and 13th and its still same. i did a vaginal examination and the doctor says he cant find anything. am not having the symptoms. am busty so its hard for me to tell. i have got whitish tings on my nipple especially the right one. earlier scan didnt show anything. i have been arguing wit the sonologist that i may be pregnant without him being able to detect. its been 11wks since the last intercourse.the last time i checked he said he saw an egg in my ovaries which shows am still fertile. my periods been on and am due 2nd or 3rd of september. could i be pregnant without knowing?
