TMI - what is this?

Ok here's a little information leading up to the picture..

AF was due 04/10

04/06 I started to feel extremely nauseous.

04/07 the nausea was so severe I couldn't eat. I had noticed some cramping and it seemed as if I was using the bathroom 10x more than I usually do. My husband even made a comment about it.

04/08 I woke up to AF(I believe). It wasn't heavy, but it wasnt lite either.

04/09 still bleeding the same

04/10 AF turned into brown spotting on tampon. I didnt have to change it as much as usual. I did wipe one red clot, but no red on tampon.

04/11 still small spots of brown discharge but no cramping and still nauseated.

We are actively ttc, but we do not keep track. We have two beautiful children, a boy who is 9 years old, and a little 2 year old drama queen! With my last two pregnancies we ended up pregnant as soon as we gave up. One resulted in an ectopic pregnancy which I lost my left tube at 9 weeks, and the other is my drama queen!

On 04/10 I wiped this. What could this be? AF only lasted 2 days with one clot and ended in very lite brown spotting. I'm not stressed at all, AF is usually normal 5-7 days long and comes on time. Could this be implantation bleeding? Is it just a short AF? I'm ok either way, just extremely curious as to what this is! Any insights help! Thank you!
