I was wondering if you think this could be implantation bleeding? I'm on the depo birth controll but me and my bf have been having active sex, not trying for a kid obviously hint the BC. We had sex on Jan 23rd and on friday Feb 3rd I had light brown/pinkish blood (small amount) on my underwear. I was looking online and it says implantation bleeding can start 10-12 days after the egg attaches to the uterus wall. I'm wondering if I should take a test or not, I think I'm over thinking this whole thing, what do you think? **Bad lighting for the picture, it's a light brownishpink**
