Just got my period back after one dose of a DEPO birth control shot, I got it back in may. And even though I'm okay with periods it just seems like my periods are really light and I thought I was pregnant when my period came and I had spotting for a day and then looked it up find that it could be implantation bleeding and I was excited then I began to feel nausea and Vomitting every morning then I work up to have in controllable Vomitting. Idk what caused this but I went to the hospital and all they did was blood work, they said I was not pregnant and they were insure of the symptoms I was having then they sent me on my way. I was and have been suffering from nausea for a couple months after but I've been taking pepto to relieve the pain. Thesemonths I have cramping and some periods don't come for weeks and there always so light and last just a few days.even though I'm an adult and I should know better. Just strange that this period was late by a week and was so light but lasted a normal amount of time then to find that I'm sporting which threw me off. I get tempted to test but eh I don't want to disappoint myself. Just seen so many stories of woman not knowing then be put in a hospital to give birth. Eh :-/ if there is someone out there that will know then I'm glad to listen. Oh my cycle starts at the beginning and end of each month and that always varies. When I thought I was pregnant it was 3months ago. I'm so lost.. Help
