I got my implant in August and my meningitis shot 2 weeks ago. Since then I have been gagging a lot, feeling sick at night, peeing loads,diarrhoea, headaches, cramping and my boobs have felt sore and swollen. I was reading about what counteracts the implant and enzyme medicines (including menengitis shots and medicines) counteract it. I've got spare HPT from when I wasn't on BC so I don't know whether to take one or wait it out until I get a period. Has anyone gotten pregnant on the Nexaplanon?!
