Hello ladies! I am 10 days post Pregnyl trigger shot (10,000 units) and still getting a faint, but definitely blue BFP on my HPT. I called the pharmacy (they specialize in fertility meds) and spoke to the nurse. She told me it should be out of my system within 7 days. I am reading conflicting things on the internet and my nurse at the RE office said 10 days. Does anyone have experience with this or know something about it? I've been using the same brand everyday so I know it's not the sensitivity changing. The line shows within 1 minute. I'm trying not to get my hopes up but it's hard!

First of all get rid of the blue tests. They're not nearly as reliable as you want. Next, continue to test with a PINK dye test like Answer or FRER until the line either disappears entirely and comes back or it starts to get darker. If the line starts to get darker it's a BFP. Some women flush Pregnyl out of their systems very quickly, but for others it can take 10-12 days. I wouldn't trust blue dye or lines that arent' getting darker. Good luck!
