Unusual: While you're not describing a high-risk timeframe, it all depends on your hormones and how short/long your ovulatory cycles can be. If you think you may be pregnant, the simplest thing to do is take an otc pregnancy test. If still unsure, see a medic who can administer a blood or urine pregnancy test.

Possible: Depends on how many days you bleed your cycle period chance of pregnancy is there.
