Hi everyone, this is my first post on here, I just need to try and save my sanity a bit.

I had my FET on Sunday 6th March, I had a pregnyl 1500 that day and again on Wed 10th, Sat 13th and last one is due tomorrow. My final BT is next Monday. From everything I have googled it says Pregnyl 1500 can be out of your system in 3 days.

I tested this morning with FR HPT and it came up BFP (wanted to start testing to monitor the lines, I am a poas addict) so I got some clear blue digital tests and did one about an hour ago and it came up BFN, there were 2 lines but from what I've read that doesn't mean anything. I don't know what to think now! Do you think this means the Pregnyl is definitely out of my system? Could the FR test this morning have been a true BFP? I do feel a bit tired, head-achy and have been a bit nauseous today which I was putting down to Pregnyl but after this test I'm not so sure, by the way I have none of my usual signs of AF coming - is this also caused by Pregnyl?

Can anyone offer some words of wisdom? I really don't know how I can hold out until Monday, I'm 12dpo today so it just seems too far away!
