My period was suppose to strt today.. but instead have light pink spotting n cramps . does that mean implantation and beginning of pregnancy?

Probably not,: it is probably the beginning of your period if you period is due to start. Wait and see what happens tomorrow. If you are not having a normal period and think you might be pregnant, do a pregnancy test. It is always better to know for sure. Your information in HealthTap does not make sense, it appears that you are 1 year old and 34 weeks pregnant - you may need to review and correct.
