患者信息： 男 34歲
I had an IUD about two years ago; the exact date was 12 July 1997.
Now my period is 20 days late.
(Last period date was 8 August. and my period usually are 30 days.)
Is it possible that I got pregnant?
I had twice abortions around 25-year-old, twice around 30-year-old. Can I take again?
If I did, what is the chance to get pregnant again?
