Okay! So Im 22 years old ovulated around November 30 my cycles are probably 30 days? Give or take? Which was also the time my bf was home for Thanksgiving. Well we had obviously had sex while he was here, we used the pull out method. Well I was supposed to start my period December 14th but I started lightly bleeding on December 12 and 13th then it STOPPED. Now my periods are pretty very regular. They usually last 5 days with heavy bleeding and crazy cramps on the first day or two but this time wasn’t normal for me. I took a pregnancy test this morning and it was Negative. Should I test again in afew days?
