Period 3 days late. Tests BFN.

My cycle is normally 28 days, on schedule. I had a medicated

<a href="https://glowing.com/glow-fertility-program">IUI</a> (clomid 50 mg, days 5-9) this month. Trigger shot on 08/05 with positive opk on 08/06.

I was due for my period on 8/21. Took several internet cheapies and all have been BFN. Anybody have a similar experience and later got their BFP?
