I have been trying to conceive. i normally have a minimum 30-31 day cycle. i am currently on cycle day 25 and began bleeding. the bleeding is not too heavy but does contain some small clots. i have abdominal cramps (relatively mild)?

Day 25:bleeding: This may just be an "early" period, but some bleeding can occur with implantation. However, clots from this are not common. If your bleeding persists, see your gyn provider for an exam and a serum HCG test in about another week or so to make sure you do not have a pregnancy in your tube.

Early ovulation?: Any cycle length between 21 and 35 days is considered normal. Perhaps you ovulated early for the first time? If the period flow doesn't feel normal, or if you develop pregnancy symptoms like nausea or breast pain, you could do a home pregnancy test. Home pregnancy tests are very accurate if it has been at least 14 days since conception.
