Ovulation spotting??

So this has never happened to me before! I got some spotting last night after sex when I wiped, I went for a scan this morning as I am due for <a href="https://glowing.com/glow-fertility-program">iui</a> this week, and I found out I’m ovulating! I have never spotted during ovulation before. Anyone ever have this and end up preggers??? My <a href="https://glowing.com/glow-fertility-program">iui</a> is scheduled for tomorrow morning (5th one, first with injection meds, no kids and ttc 3 years). Any advise or feedback??? Really hoping this time is it!
