I'm having my first period since having the contraceptive implant fitted 5 weeks ago. I have been bleeding for 7 days now. Just had a shower and passed a big 'thing'. It's not like a bloody clot, but like a big sack of skin with a hole in it. There doesn' seem to be anything in the sack. It's a pinky brown colour and I haven't got a clue what the hell it is. I know I wasn't pregnant when I had the implant fitted, and I tested again the week after the implant (negative).
Do I need to see a doctor?
What could it be?
