Is there a problem with the pair of contact lenses?
I am male, 31 and have extreme myopia. Left eye is -19 and right eye is -21. I was wearing left -14 and right -16 glasses. Now I went to Doctor and got the prescription. He advised me to go for contact lenses. When I tried the contact lenses, I could see distance things clearly but near vision is quite blurry and can not see or read.
The doctor said that high myopes have this problem due to high prescription and you should use reading glasses or progressive lense glasses for near vision along with contact lenses. Please verify whether the doctor is right or is there a problem with the contact lenses? Also suggest me what should I do.

That is quite a jump in prescription, how quickly did your vision change that much? Before the new prescription, didn't you have trouble functioning with essentially -5D of myopia, putting your best focal point at 20 cm = 7.87 inches? I'm guessing you didn't need to drive? I'm just wondering if the change was sudden, if it might indicate other eye issues which might go along with the problem with seeing near while wearing distance correction.
As people age they gradually lose the ability for their eye to change focus from far to near, the number of diopters the eye can change focus goes down over time. When people corrected for good distance vision start to experience problems seeing near well enough without additional correction, its called presbyopia, its why often you'll see older people needing reading glasses and why they sell readers over the counter in many stores.
However usually in the US (I don't know what country you are in), presbyopia issues aren't usually evident until the early-mid forties, though a quick check shows in some countries, the age is a bit lower, but for most modern countries (I don't know where you are) you seem young to have this issue (though some do). Your description suggests you may have "premature presbyopia" or "early onset presbyopia", which has a number of causes they can consider. Oddly I see hyperopia suggested as a potential risk factor, but not high myopia, though some suggest those doing more near work may be at risk, it isn't clear from a quick skim if that is the case.
Most high myopes do find vision better with contacts, with the added advantage with presbyopia that you can have a pair of reading glasses you put over them for near. If you have two distances you wish to see like a computer and reading closer in, some use bifocals, trifocals, or progressive glasses (called varifocals in some countries), which are sometimes described as "no-line-bifocals" but they may provide a continuous range of vision rather than just 2 focal points.
If you don't use your distance vision much, you could also leave yourself undercorrected with contacts to see better at intermediate or near, and then wear glasses over your contacts for distance vision.
In my case I preferred wearing multifocal contacts, which let you see distance as well as near without needing to look in a different direction like with glasses, and without the need to put on readers. There are tradeoffs, like reduced vision in dim light, but I didn't mind that. Some may see their distance vision not be quite as crisp with a multifocal, though if you managed without good distance correction for a while I'm suspecting that isn't a big concern. Others use "monovision", one eye focused in near to be able to read, which however reduces depth perception since you are using one eye more than another, though most people adapt to it well and don't notice. I preferred multifocals, and figured full depth perception is safer in many contexts than monovision (e.g. pilots aren't allowed to fly with monovision correction in the US, and studies show an increased risk of falls in the elderly with monovision).

I tried the monovision approach before with contacts and never liked it. I opted instead for distance correction and used OTC readers for close up work.
That is correct. You may need reading glasses or have to do monovision where your non dominant eye is undercorrected for near vision

Will the same happen if I go for glasses in place of contact lenses? What if I go for some intermediate correction like Left -17 and right - 19? Will the near vision be same blurred? I am asking this as I was under corrected by -5D for long time?
I am a PhD candidate so I need near vision frequently and intermediate vision.
What is your age? Even people that don't need glasses start to have problems with near in early to mid 40's.
My age is 31 and I am very much concerned about future. Please suggest something.
I suspect you see a great deal better with contacts than with glasses. If you are unable to read with them on then the ophthalmologist or optometrist that fits you can prescribe glasses (thin) in a progressive multifocal to be worn over them.
Thank you Sir for your expert advice
