Hay, that's stressful talaga! Have you tried calling the public hospitals directly in Cavite like Cavite Medical Center or the municipal hospitals sa nearby towns, sometimes may slots pa kahit ang main branches puno na, at mas affordable talaga. A few of us here went to provincial hospitals outside the main areas and nahanap namin slots plus better prices, so it's really worth calling around and asking kung saan pa may available dates para sa CS mo, good luck, mama!
