Hi,I'm 33 I had the implant contraceptive for 3 yrs and had it removed and replaced on the 25th may my period was then due on the 6th june but it never came from then on I felt pregnant ( I have two children) I had it removed because I was convinced that it was down to the implant, then on the 22 nd June I bleed for four hours, one yesterday 16th July I started Again however it was the same on for a few hours then off again and the same again today, I have done countless HPT's and they are all negative. ( which is ideal because my partner is due to have a vasectomy) my bleeding is also alot lighter an a different colour it's more a pink! Please help me
