Before getting the implant, because of the expense involved to the health unit, I got two injections of the Norplant. Bring that they are the same hormones and close levels. I tolerated both well, having a slight period for nearly 3 weeks constant then no periods until it ran out (only supposed to last 3 months.) I then received the Nexplanon injection. Again, I had a slight period for 3-4 wks, then I was in heaven without a period for nearly 2 years. Suddenly, for no reason, I began bleeding again, having actually periods. Is this normal? Does this mean my hormone levels are still high enough to not get pregnant? That is my largest concern. I have an appointment in 3 wks and until then plan on using protection with my ten plus year partner
