I got Nexplanon back early in December 2017, and now (2/4/18) I have a brown almost muddy discharge coming from my vagina. It does not have a smell and when I touch it, it almost feels like jello, it’s not sticky or runny it’s clumpy. I did have a period last month January but it was short and I have been getting cramps lately but no period yet for February. I just get nervous and I need to ensure nothing is wrong.
