Hi
ihad my coil taken out on the 7th sSeptember and got what I thought was my period on the 9th . This lasted for 3 days and was quite heavy.

Since it finished I've been having a fluttery feeling Iin my belly, sore breasts, feeling sick and having headaches.ive had unprotected sex aabout 4 times since having the coil removed

today I have been having brown blood coming out

I was just wwondering if you could help me out with this and share some light on what xcould be happening?

Thank you
