I inseminated on Jan 4 & tested 2 weeks after on the 18th (the day my period was expected) & both tests came back negative. I didn’t know much about vvfl so I’m not sure if there was one or not. My period is now 6 days late and I’m so nervous to take another test. I am supposed to take 1 tomorrow. Considering it’s been 3 weeks since I ovulated would it still be possible to get a vvfl on tomorrow’s test ?
