Glow 😖

Has glow really been helping you guys with trying to get pregnant ? I finally had a period after depo and me and my man are ready to start trying .. Glow said my most fertile day is April 14th .. But we aren't able to do anything that day .. So we did it April 12th with hope that the sperm will live until I'm really fertile.. But I wanted to get other opinions so i looked up and ovulation calendar on google and they all told me I'm really fertile on April 12th .. Which would be great .. But has glow ever told you wrong ??
