I have been on the contraceptive injection since January now and the nurse did say to me over 80% of women stop bleeding once they have been on it, and I was with in that 80% so I have not bleed or had a period since I have been on it. But lately I am feeling a really strong heartbeat in my stomach it's been like this for a couple of weeks now and you can even see the heartbeat moving with my pulse. I did research this and some topics came up with this relating to anxiety but they say this is for thin people, I wouldn't say I am thin, but neither fat so I am left confused of what this could be?
