Ok so 10 days ago I had my implant taken out an they said fertility is normal more or less straight away. I had sex the day after which was 9 days ago. I haven't ha a period and that was due 4 days after I had the implant out (5 days ago) . The last time I had a period was four weeks ago. I have had diarrhoea, sickness . Very low left pain in my abdomen which hurt during sex I had this for two days. I am nauseous , have headaches and extremely horny and   Have sore nipples. I had slight bleeding 4 or 5 days ago .. The tiniest bright red bleeding. I use a tampon but didn't continue bleeding.. Could it be possible it's implantation bleeding hence my abdominal pain?
