QuestionQUESTION: The last three months my period has been coming every 6 weeks. I had sex about 28 days ago and my last period started 38 days ago and still no sign of it. A pregnancy test today was negative. Could I be pregnant?
ANSWER: If your period has been coming regularly every 6 weeks, then you should not be expecting to see it for another 4 days at least. Pregnancy tests may not turn positive until the first day of a missed period, so taking a test and seeing a negative now doesn't mean much. However, if your cycles are 42 days long, then you are probably ovulating somewhere between days 24 and 31. Since you had sex on day 10, it's pretty unlikely that you would be pregnant unless your cycle length suddenly changed this month.
Wait at least 5 more days. If you don't see your period by then, test again.

QUESTION: I have begun bleeding, but it is very light compared to my regular period. I am in the third day of it and it is red in color. Is there any chance this could be implantation or just a light period?
AnswerTheoretically, it could be either one. Go ahead and take another pregnancy test. If it comes up negative, and your flow has not increased to normal levels, talk with your doctor about a quantitative HCG blood test. This will definitely show whether or not you are pregnant, even at this early stage, and should help put your mind at ease.
