Not likely: While I suppose, given some facts like unprotected sex near ovulation, a positive HPT and a missed period that it is possible, it's not likely. Any period is probably going to flush out an egg along w/ it. If your other complaints are worsening, or if your periods continue to be irregular - have an exam. Use protection for any sex. Cut back on over-eating, avoid salt and drink water - be active.
