Ivf trigger and hpt

What did you trigger with?

My trigger will be hcg 5000U and Lupron 5mg

How long will the trigger give me false positive HPT. Planning on fresh transfer

During my <a href="https://glowing.com/glow-fertility-program">IUI</a> ovidrel trigger stayed in me 10-12 days. Is the <a href="https://glowing.com/glow-fertility-program">Ivf</a> hcg trigger same?

Im confused by post transfer ladies taking hpt as early as 5-8 days after transfer, wouldn’t it possibly be residual trigger ?

Obviously first time IVFer, thanks for clarifying anyone out there

Thanks !!!
