About two months ago I had unprotected sex with my boyfriend. Right about the time I started BC. I have never missed a period or ever been late ever in my life. I started light brown spotting about a week after for about 6 days. Then I missed my period that was due in June. I've had pretty much all the symptoms of pregnancy, but it could be depression symptoms. I had light bleeding when my period was due in July, but it was not the regular bleeding I usually have, it was watery and light. Could I be pregnant?
