No in India , girl should be 18 to get married...
Yeah, 15 is that even legal? was the first thing I thought, but Im guessing Indian or Middle eastern descent, in which case itd be ok'd by parents...
Topic at hand, yes, it could be that shes a bit young, though definitely not unheard of. Depending on your situation, id recommend both be seen by a doctor.
well I'm not sure where you're from, I'm assuming NOT the US. Your wife is only 15??? Her age may have something to do with it. OR maybe SHE is the reason and NOT you. You may want to get her checked out.
it is illegal to have sex with a child under the age of 16/17 depending on the country
Even if your wife ovulated theres only a 20%chance each month for her to get pregnant. If she doesn't know when she ovulates then she needs to use ovulation predictor kits. You're prob having sex at the wrong time
