Am I pregnant????

Kaitlyn

So I got my nexplanon out 3 months ago. I haven’t had a period since. I started getting nauseous and feeling weird so I took a test(or 3) the two line test are positive ish. One of them is VERY faint and hard to see. But the clear blue is not pregnant. Do you think it’s to early for the clear blue? Or do the blue line ones just suck major ass? HELP.
