It would be reasonable to take a pregnancy test now based on your symptoms. It does make it hard when you have very irregular periods as you note. If your test is negative, but you still don't get your period, wait two days then re-take the test. If it is still negative you could see your doctor and possibly get a blood pregnancy test, which is more accurate. In general, the pregnancy test can become positive 10 days after pregnancy though every womans hormone level of pregnancy (HCG) can be a little different at different stages of the pregnancy.

A blood test for HCG, at 3 weeks after the fruitful episode of sex is generally accurate.
