Husband and i are trying to conceive since oct. i am now 13 days late. went to the dr on 27 th blood test negative. normally regular.wats up. im 23?

Late on menses: There are a number of reasons to explain a late menses including: pregnancy, irregular cycle, and a persistent ovarian cyst. Wait another week and if the pregnancy test is still negative make an appt with your gyn, and i would suggest a sonogram.

May be normal: Maximum pregnancy rates in humans are about 20% per month, and 85% per year, therefore you may just need to try longer. The average woman misses a period once a year. If you are concerned, it is totally appropriate to be evaluated.
