First day of my period was november 12 and had unprotected sex on november 28th. not sure if i was ovulating or not. took morning after pill the next day. on dec. 5 &6 had tender breasts and usually inverted nipple kept sticking out. am i pregnant?

Difficult to speculate beyond probably not. Pl get a preg test.

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.
