Implantation bleeding ??

Megan

Hey everyone! So I have a cycle that’s last around 23 days and it’s always regular. I got some light spotting approx 9 days after my period ended. It was light at first and brownish for 2 days. Then it was quite red and I saw some clots.it lasted in total about 5 days.

So I am thinking it was implantation bleeding but something happened and the pregnancy never happened. I say this because my period is always on time and I have never bled that early after a period ended.

So now according to my cycle on glow I should have started my proper period on the 15th but it hasn’t come. I 100% don’t think I am pregnant I was just curious if it was normal to have an implantation bleeding that failed and then a late period?

Hope this makes sense!! Thank you :)
