I haven't has sex since around the beginning of October and had a light period October 21, then another in November 19 and another in December (don't remember the date). they were all really light lasting 2 or 3 days, which is odd because usually they are heavy at least lasting 3 days. I haven't had a period since December. and i've been having pregnancy symptoms since October (i.e. sore breast/nipples, nausea, frequent urination, back pain, etc.) i took three hpt in October when i started feeling the symptoms but all 3 came back negative and one more hpt in November and that came back negative also. could i be pregnant? is there something wrong with me? i just read somewhere you could still have a 'period' while you were pregnant. should i take another hpt? has anyone else had this? i don't know what i should do.
