Hi, I had sex on 15 Feb, 2014 and we used protection, after sex, we had confusion that whether some amount of sperm got inside, so I took a contraceptive pill. On March, I did a pregnancy test, it was negative.. Today, I checked from the first urine sample, I got the results, the test was negative, but some pink lines appeared on HCG column Please tell me, am I pregnant or not? Still I didn t get my periods. Please help.. Hoping for a favorable response. Thanks
