<s>[INST] I got my period on December 12th, I am trying to conceive but not 100% sure if I was ovulating. Had sex from December 19th-30th trying to get pregnant. Its exactly one week before my expected period but I am anxious and curious if it was a good time to try or what I can do for next time. I did experience dark red spotting (which from my research could be implementation bleeding?) but it only lasted 3 days. Please help! [/INST] if your periods are regular, you almost certainly are ovulating.  if you count the first day of your period as day 1, then you usually ovulate around day 12.  if you start having axe at day 10, and have sec every other day until say 20 or so, you should get pregnant.  though sometimes it may take six months or more so don't give up! good luck! </s>
