About how long should you wait after ovulation to take a preg test? I ovulated about two weeks ago and my af which is regularly on time should've came on 4 days ago. According to glow and a few apps I use. I'm having symptoms but got three bfn on the dollar store test..... I'm so frustrated! If I'm preg I'm so ready to tell my bf, kids and family. The wait of knowing. Smh!
