Suggest Treatment For Suicidal Thoughts, Anxiety And Irregular Periods

Question: I have no relevant allergies nor have I ever had an STD and have dilligently been using protection ever since I began engaging in sexual acts with others. I have the nexplanon implant and have had it since march of the presemt year. I have experienced moodiness and thoughts of suicide, bouts of increased anxiety and irregular periods. I kept the implant in because it is effective. Or so I thought. I may be pregnant or I may have some issue with periods im not aware about. I have gone from a 34 to a 36 D and the change has been noticable to my significant other. I have had strange cravings and smells that usually make me hungry make me ill now. It seems as though i may be pregnant because of this and my increased nausea. I have had strange discharge a mix of bloody clots with veins and pink discharge and brown like old blood, very light. Ive taken 5 pregnancy tests, all negative. I dont know what to do with these new and awful cramps i sometimes get. Could i be pregnant, is this implant just not for me? I dont know if a gynecologist will check me if im still bloody. I had a faint positive but it may just be an eval line. This has been going on for a mo th now. I also have issues passing stool where i never have before. Pictures are of last big clot. No more big clots since. Just pink brown and that.
