Help...?

So I was due my period last Sunday it didn’t arrive, then on Monday I had about an hour of very very light pink blood. Then nothing.

Come Wednesday and I have more spotting for about an hour then nothing again.

Then yesterday morning I thought my period had finally arrived, bright red blood, cramps, passing small clots. The lot.

Then it stopped and now... nothing!

I’m defiantly not pregnant (same sex relationship) and waiting on my cycle so that I can start IUI treatment.

What’s going on? 😞😕
