Is any one else TTC although hubby has a vasectomy?

I know sounds silly right? My husband and I have been married for about a year. He had his vasectomy about 4 years ago because him and his ex wife had 2 children. Well now I found the love of my life and would love nothing more but to have a baby with him. We can't afford a reversal or sperm aspiration as of now. Anywho I just started charting my periods 3 months ago. My cycle is normally 30 days and my period is around 4 (although the past 2 months it's been VERY light and only 1.5 days long). I've been having pregnancy symptoms i.e. sore tender brests, AF like cramps(I had my first pregnancy), queasy, high soft cervix. I'm on CD30, supposed to get AF tomorrow and praying she never shows up. It's so hard knowing we might not ever be able to concieve the all natuarl way. Any view points at all, I'd truely appreciate :) ***BABY DUST TO ALL***
