Hellllp: Has anyone had this???

Ok, so TTC, 1st cycle and I have a very regular 28 day cycle. My FF chart says I ovulated on CD 14 and now it's CD 17 and I have some light bleeding. Too early for implantation bleeding I'm pretty sure. Also have some minor back ache. (https://www.fertilityfriend.com/home/26f289/rss3181.xml)

Some extra info is that I went for a chiropractic adjustment in CD 13 and wondering if that may be bringing on an early period because the chiro pushed really hard on my ovary area to check a hip muscle and it really hurt. (Not sure if this has anything to do with it)

The bleeding is very light and so far it's only been 4 hours since I first noticed, kinda reddish, not brown or old looking blood. I also have very slight backache mainly on the right side.

Can anyone shed some light, had a similiar experience? Is it an early period?

 

Thanks SarahMelissa, I did do some googling and that was something that came up, will do some further investigation. Just unusual as I've never had it before.
