I underwent IUI this month. Thursday 11th was trigger (13 days ago) IUI on Saturday 13th (11 days ago). Got a very faint positive on Monday 22nd (9dpiui) on FRER. I have gotten a bfp yesterday and today. Line is identical and much darker than 9dpiui both days. My trigger was 250mg ovidrelle. I don't want to get my hopes up given previous miscarriages but is there a chance it could still be trigger or could it be a proper bfp
