False positive?

Erica

Just wanted to get opinions...I am due to have my hcg blood work drawn tomorrow (2 weeks after having <a href="https://glowing.com/glow-fertility-program">iui</a>). I know you're not supposed to take a home test or try not to. If you do, can it still be false positive even just a day before bloodwork is done? Or if it's positive is it really positive?

Thanks!!
