Wanting another baby

Recently my periods have been very out of wack. I didn’t have a period for 3 months. At first I was convinced I was pregnant. Went for a blood test and everything and it turned out my body wasn’t ovulating. I waited and waited and my period finally came. Now I’m 12 days late again. Took a test and it was negative. I feel like it’s a little early for another baby and so does my husband but we want at least two little munchkins. He wants three but idk if it would be possible with what’s going on. I’m wanting to try for another one now bc it will take a few months for me to get pregnant but he wants to wait until April or May. I’m terrified that if we wait that long even though it’s only a few months that it’ll be too late and I won’t be able to have anymore.
