Natalia

I recently got my birth control implant removed the 17th, my fiancé and I had sex the 23 and 30th and he came inside of me both Rhône’s multiple times, I didn’t get my period with the implant and hadn’t had the chance to get one after, anyone know when I should test?i haven’t had my period in over a a year, I should have got it within a month or the next month after, I’ve been having mild cramping and fatigue (Cramping since Tuesday) I’ve also felt nauseous without throwing up I have no idea when I should test I’m new to all of this and I don’t know when because of the different dates and not having a period
