OK mommies, I have a question. how long did it take before you found out you were pregnant? and how did you find out? I took four at home tests after I missed my period in April, two at one hospital where they told me I wasn't pregnant and had dysfunctional uterine bleeding. I found out that I was pregnant when I was almost 3 months and went to a different hospital.
