Hi. I am currently on my R1P2 day 18 of my hcg drops. And lost 7kgs. My period is due yesterday but hasn t come until now. We had unprotected sex during my fertile week and yesterday i had pinkish brown discharges after sex. And so this morning after sex. But it was too little that it shows just right after i wipe. Althroughout the day, there was nothing. A week before my expected period, my breast were tender and nipples were a bit sore which normally happens a week before my period. i didn t take my hcg doses yesterday for a fear of being pregnant and harming the baby. When is the best time to do a home pregnancy test. Your reply is much appreciated. Thank you.
