Had intercourse last month on 12th and my periods were from 3rd-9th, usually regular. I took unwanted 72 within few hours of intercourse. Started bleeding some hours later and continued for some days. Then i think my periods again started on 18th till 22nd. I didn't pregna news test on 26th... It was negative (single line). Then some days later i did another prega news and again it was negative. Then on 4th of this month i went for blood test. My Beta HCG level is less than 1.2 mIU/ml. Am i pregnant and what test should i go for??
