Last year in may i had gotten on nexplanon and i kept it in for a year, i had it taken out may 9th of this year. May 12th i started my period and that lasted until the 16th.... i experienced pregnancy like symptoms here and there but always got Negative pregnancy test . I had my period again on the 7th and it lasted until the 12th, since last night i have been experiencing sore sensitive breast and mild cramping.... could this come from me being pregnant or from ovulation? HELP !
