Is it possible to get pregnant if i'm overweight and in my third year of having it? It's not supposed to come out for a few more months, but i'm worried. And I know they didn't do studies to see if it worked on overweight women. According to Glow my average cycle days have been getting longer, and i'm worried maybe the chemicals are running out. I'm like 2 weeks late on my period, but it's usually irregular, although recently (past few months) it's been more regular. I've been having diarrhea and i've been pretty nauseous for the past few days. Thoughts? I'm really worried. Is it even possible to get pregnant on nexplanon?
