Hi i was last on the depo in january of 2013. I am 32 years old and have went back for any of my injections for about five months now. My last period was May 31st until June 5th. Me and my husband have been very active alot but I still have negative pregancy tests. My period did not come on and now it's July. I am having crazy food cravings, constipation, and frequent urination. I don't know whats happening and I believe if I go to the clinic and get a blood test, it's gonna say negative. I am totally confused maybe I am pregnant, or maybe not. Help!!
