I recently just went off the depo shot after a little over a year. My last shot was due October 6th, but im trying to get pregnant. At the end of August i was on antibiotics for clymadia and herpes due to my partner and i not knowing we had it. Im showing signs of being pregnant but three home tests have said negative. Could i be pregnant? Im currently 5'7" and weigh 185 pounds. My past medical history is clean.
