pregnant?? and how much is too much exercise?

[yzebella]

I'm 23 and just recently got married. My period is 14 day late as of today, I've never been this late before. I've had light lower back pain and some light cramping for the past 5-6 days, other than that I've had no other signs of pregnancy. I took a HPT yesterday and it came back negative. Could I still be pregnant? Also, I'm a Division 1 track athlete (pole-vault) and am currently in full training...how much exercise is too much while pregnant?
thanks!

The thing I would be concerned with your sport would be the impact while landing...you are supose to avoid and impact sports while pregnant. As far as other training I think a lot depends on how much you do before you get pregnant...pregnancy is not a time to Start a new exercise. Could your training be affecting your period? Some women take longer to get a positive on a hpt so If it were me, I'd go see my Dr. especially considering that you are in the middle of full training.

Sometimes hard exercise can cause amenorrea (absense of period).  You could also be pregnant but maybe you should go to Dr. to get blood test.  Also I think that you can exercise pretty hard but not exceed 145bpm if you are pregnant.  If you are pregnant I think a high impact sport like jumping etc. might not be very advisable in later stages.  Talk to your Doctor they will tell you what not to do.
