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?
