I have recently had implanon removed after 3.5yrs. I was having difficulty with mood swings, headaches and lack of libido, and I noticed that on the 18th of every month for a little while before removal I felt like I was having a period without actually bleeding. I want to concieve again, should I go off this date to predict ovulation or do I just have continious intercourse in the meantime in hope I am ovulating now? I am yet to have a period as I have only just removed the implant. I had no bleeding while I had the implant, just irregular spotting when I was stressed.
