Hello - yes, of course it is possible that your cat may be pregnant. This depends on there having being a boy cat around at just the right moment, on her being in or approaching oestrus and there being time and / or circumstance for mating to arise. If you speak to your vets, they can talk you through various options which may include booking your cat in for a spey operation as early as possible, perhaps even before a pregnancy is detectable, or considering chemical contraception measures if they are a viable option where you are, or leaving things well alone to see whether or not a pregnancy develops (perhaps with a scan after an appropriate interval). Different vets and different owners have different ideas and beliefs, so that is something to discuss between the two of you. Wishing you all the very best outcome, whatever that happens to be.
