I had the Implanon inserted october 2013. At first I really thought it was awesome but then came the mood swings, weight gain, and I had no sex drive anymore. The lady told me to come back in 6 months if I did not like it so I immediately did. After it was removed I immediately got my period... but this one lasted me for about 2 1/2 weeks. ( which I thought was normal because of the fact that I hadnt had it for about 4 months ) last month *February* I missed my period so I freaked out and took a pregnancy test which came out negative. My friend told me to wait another 2 weeks and take another. I did that and that one came out negative also. Today is march 4 and I still havent had my period but my breasts have been really sore and sensative... what does this all mean? Is it normal to miss your period after? Is it okay to be irregular? Ive been stressing out so if someone could help me that'd be awesome.
