Hello ladies wanted to here if anybody has any information that can help me get threw this.

So on Saturday 8th my hubby and I did out 3rd <a href="https://glowing.com/glow-fertility-program">IUI</a>, but this time with fertility injections and today is 6th day, woke up with cramps & started to spot a bit, got a bit more bleeding, not enough to use a tampon or a pad, just a panty liner. Do you think the <a href="https://glowing.com/glow-fertility-program">iui</a> didn't work? Or is this normal we didn't have this the last 2 times .
