Three days early bleeding with breast discharge/ abdominal painincreased discharge , head ache, tiredness can be- - Mostly conception ( with unprotected sex).. & implantation bleeding cn occure around expected date of pregnancy. The bleeding is scanty, & woman is normal part from getting tense. - Pregnancy test ( blood test around date of menses/ urine test after 8 days delay in periods ).. would be confirming pregnancy. - Sometimes pregnancy like signs are seen without being pregnant( post illness , weakness,ovarian/ thyroid problems, PCOD) If pregnancy test turns -ve.. investigations to find proper cause & have specific treatment is the solution to recover. thanks.
