Unprotected sex on 19th march had i pill within too hours , had bleeding for 3 day on 23rd march , took thtee pregnancy test ( 1,10 , 16 th april ) all were negative, haven't had any symptoms ( except minor back pains)  but experienced tissue and white chunks in urine from past 3 days and white discharge yesterday it's 30 April still haven't had my periods , also i have a history of irregular cycle of periods . So is it a late period ? or undetectable pregnancy ? ... how long should i wait , should i consider abortion pills as having a blood test in lockdown is little hard ? What can i do to induce periods?
