We've been trying for a year

Christian
Me & fiance have been trying to conceive for a whole year now with no luck. My first two kids are from a previous relationship and he thinks he can't have kids anymore & I choose to think otherwise. I am very fertile as my two kids came back to back right after a miscarriage. So I'm starting to really believe him..... even though I don't want to. My periods here lately have been very strange Jan. to Feb. I didn't have one for 45 days I just knew I was pregnant but getting false negatives. I was heartbroken as many of you could imagine when Aunt Flo decided to visit. Then Feb. to  March 33 days and now March to April I am now on day 38 but I won't let my hopes get up and I refuse to take a test because I am afraid of a negative result. I keep telling myself stop wanting it so bad & it'll happen but that's nearly impossible!
