Hi I'm a little lost with myself and looking for advice...I had my son Aug 2015 had a little period in the Sept 2015 then got the implant in which resulted in no periods. I hot it taken our three weeks ago. We've had unprotected sex a few times within a few days. The last few days I've been totally exhausted I can't function...cramps and fuzzy head nippers have been sore...I've just been to loo and had a light red bleed....Nothing since. Could it be pregnancy? Or more likely my period? Xx
