Hi, MissLady, this is June; I assume you posted this in January somewhere else? Anyway, as I said when we discussed things before, if your cycles were perfect and you could count on having ovulated on Day 14, or if your ultrasound was earlier, you could be sure this was your husband/boyfriend's baby. The odds favor it. But unfortunately, it is too late to get a dating ultrasound that would make it clearer or guaranteed.
