Okay I have a question for your ladies. I had one depo injected a little over 4 months ago. A few days after I was due for my last injection I took a OPK and it was positive for like 2 days. Then a few weeks later I took another one. positive. Why could it be doing this? I haven't had a period but I have a ton of watery discharge sorry for TMI. Has anyone else heard of a lot of OPKs being positive?
