Merhaba, Aşağıdaki sliderda col-md-3 olan yer bir rowun içerin tek başına dönüyor. Ben rowun içerisinde aynı anda 4 tane dönmesini istiyorum. Nasıl yapabilirim?

<section class="mt-5">
<div class="container-fluid mt-5">
<div class="row mt-5">
<div class="col-md-12">
    <h4 class="urun-gruplari-baslik mt-5 mb-4">ÜRÜN GRUPLARI</h4>
    <div class="divider-urun-gruplari"></div>
            <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">
                <div class="carousel-inner">
                        <?php $kategori_oku = $mk_db->oku("urun_kat", "", "sira DESC");
                            $slider_sayisi = $mk_sayi;
                            foreach ($kategori_oku as $kategori){$counter2++;?>
                            <div class="carousel-item<?php if($counter2 <= 1){echo " active"; } ?>">
                                <div class="row col-md-12 mt-3">
                                    <?php if($counter2 <= 4){?>
                                    <div class="col-md-3">
                                        <a class="urun-linki" href="<?=$ayar_sitelink.'liste/'.$kategori['seo'].'/'?>" >
                                            <img src="<? echo $ayar_sitelink.'upload/kategori/'.$kategori["id"];?>.jpg" class="" alt="<? echo $kategori["ad"];?>">
                                            <p class="urun-isimleri text-center"><? echo $kategori["ad"];?></p>
                                        </a>
                                    </div>
                                    <? } ?>
                                </div>
                            </div>
                            <?php } ?>
                </div>
            <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
                <span class="carousel-control-prev-icon" aria-hidden="true"></span>
