Husband’s ejaculation

So for starters, it should be known we are trying to conceive right now. Question for all the ladies, do you notice that you have semen leak out of your vagina after sex? I️ notice this regularly, however the last two times we had sex I️ did not notice anything leaking out. It was the second and 3rd night in a row, which isn’t always normal for us. I️ thought maybe he didn’t finish but told me he did. Is this cause for concern that I️ didn’t notice anything afterwards? Do men produce different amounts?
