Hopeful but afraid of disappointment

So for the past month I have had several people tell me that they had dreams that I was pregnant. 1 person even told me husband that it's about time for him to have a child of his own. Then on Easter Sunday, I had someone come up to me and put their hand on my belly and said when?this person has not seen me in a few months.  Now with that being said let me just say that it's got me nervous because 8 yrs ago I had my tubes clamped before my husband came along. I already have 3 beautiful children. It would be a huge blessing to be able to be pregnant and give my husband his 1st biological child. Looking for support because I'm not due for AF till 4/14. Thank you ladies.
