There is a reason why you can’t go to the drug store and get a quick over the counter blood test?
Moon is VOC so probably not pregnant, but I surely would not use astrology to predict medical conditions.
If the answer to pregnancy is related to the fruitful horoscope, then no.
Why do I say this? Because some depend only on the presence of the ruling planets in fruitful homes. Perhaps this is not accurate.
But if the answer to your question can be taken from the communications of the planets and the presence of the ruler of the first house in the fifth house, with the ruler of the fifth house, then the answer is yes, you are pregnant.
