I have been spotting for three days lightly. It's mid cycle, ovulated a few days ago. Googled it seems like it would be normal mid cycle spotting but I've never had that before and I'm almost 32. Implantation spotting couldn't happen this early right? According to what I've read it wouldn't happen for at least another 1-1.5 weeks. Anything I should worry about, could it be anything else?
