So I found out about the preseed and many success stories, and I bought my first pack. I'm so excited, but my husband is going to school for nearly 2 months. As am I, for 1 month. I get off my cycle within the next couple days and he leaves Tuesday so we have 2 days. His last day of school is on my birthday, November 20th. But I'm just wondering, should we try this once before he leaves or after he gets back. Remember I'll be in school for 1 month. And we are both nervous yet so excited.
