Pregnant on the implant ?

I've had the implant for a little under a year, it's curved and shifted a lot (after it had already settled). Anyway since I had it I haven't had any periods, but I recently moved in with my partner so we have been a lot more active. I know it's probably nothing but I had a little tiny bit of bleeding (haven't had a period since so this worried me) last night had dull minor cramps and lower back ache. And sorry if tmi but the opening of my lady area feels like it was being pulled out ! (Sorry 😂 only way I can describe it) I have so much more saliva than normal and constantly feeling bloated. And randomly feeling nauseous. I know I'm probably reading into it too much. Being stressed for other reasons doesn't help too. I will do a test when I have a chance. But was wondering if anyone could shed some light on my situation. Many thanks ladies ! Xxxxx
