Arulkumar, I am not familiar with Vedic astrology, but you could use this question as a horary question if you like. It is very very difficult to predict a pregnancy from a birthchart and you almost need to be a clairvoyant.
The nearest you can get is to ask if you can have children to start off with. We cannot predict a pregnancy if we dont know if you can get pregnant. Or maybe your husband is unable to have children. There could be so many factors, that this question of yours is probably not answerable. I dont know how a Vedic astrologer goes about this, but in Wester astrology it is most difficult. Same thing as when someone asks: when will I marry? Very often you see an aspect, progressed, which very much looks like it and nothing happens. Or instead of a wedding you get a fantastic promotion, all very happy events, shown by the same sort of planets, so really, I dont think you will get an answer which will satisfy you I'm afraid.
In this forum, we are all asked to give our own interpretation to our questions because this is a learning forum (for this reason also, predicting when you can get pregnant is highly difficult for students and even for experts).
In this forum you are not expected to get a free reading. For that you will have to go to a fortune teller or a medium. Here we all learn and we learn by doing.
Now your question is a very difficult one, but you could always try to look at your 5th house and your husbands, to see if maybe, children are indicated and tell us what you think. It does not matter if you make mistakes. That is how one learns after all.
I will move this thread to the Greenhorn Lounge where all threads are being moved to when no self interpretation (attempt at least) is given by the poster.
