I've been ill recently, migraines and nausea mostly. I haven't been sleeping well. I also started my period, which due to my birth control I shouldn't behaving for a few months. The blood is much darker than normal, and slightly thicker. My cramps are not to bad. My nurse-practitioner had attributed everything to stress. I lost my virginity a couple of weeks ago. Considering the time frame, I don't think it's Implantation Bleeding, because the 'period' didn't start for nearly a week afterwords(also Birth control and condom). Logically I'm fairly sure it's not, but the illogical part of my brain is screaming in terror. I'm actually really terrified, and any help would be useful.
