Hi guys, this is my (I dunno) millionth cycle ttc. But this is my first IUI. In the past we have done timed intercourse with femara and that has resulted in 2 miscarriages and numerous bfn. In this cycle we did femara day 3-7 and then triggered with ovidrel and IUI. Today is 10dpo and 12 days post trigger. I tested a curve frer last night (9dpo at about 5pm) and it was a faint positive and then this morning (10dpo at around 6am) I did another test and it was positive a bit darker too may be. In the meantime on 8dpo I did an amazon cheapie that was a very very faint positive. I did the cheapie again last night (9dpo) and that was much darker positive and then I did the cheapie again this morning with the frer and again the result is much fainter bfp. Should I be cautiously happy or is this really a bfp. I am attaching pics from the frer and cheapie. Please help.

I don't know much about IUI but I read about leaving testing until 14 days after a trigger shot? I think? I'm pretty hopeless at this tbh, but what I was thinking was if you are seeing progression, which it looks as if there is to me, then I would have thought that would be an actual bfp
