First time ttc...

So, I am new to this...

A couple of weeks ago my S.O. and I were pretty positive that I was pregnant, I had all symptoms.. it threw us off.. we never thought about having a child.. in all of my puking and not ever feeling well. And one day I hated the sight or smell of food and the next I could eat a cow.. we started getting really excited! I finally took a test and it was negative... both of us were upset.. but we realized we are ready to try!!!

The only thing is... I'm super irregular... and I was hoping maybe someone could share some wisdom/advise. Any vitamins I should be talking. Anything he should be taking or doing? Anything is helpful. THANK YOU!!!
