2weeks before had a sex without protection just inand out 2-3times, before that i masturbated, is it possible to become pregnant, if yes what should i do to get rid of this. thanks in advance?

Any sexual contact that involves an erect penis entering the vagina has the potential for pregnancy. It only takes one sperm and an erect penis will have them in any secretions involved in the contact. Two weeks later is too late to ask this question. You are either pregnant or not. Time will tell.

Conception occurs within day or so of the sex. It takes about 3 weeks for the embryo to make enough HCG for a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. If the result is negative repeat the test in 4-5 days. Use first morning urine and follow instructions for the test carefully.
