Depo Provera Birth Control Shot - Am I Pregnant??

[shanloughrige]

So on June 3rd, I received my first Depo Provera injection while on my period, so I was told it would be effective immediately. I felt fine, a little queasy for a week or so after, but no big deal. Approximately 22 days later on June 25th, I had unprotected sex with my boyfriend, while he typically withdrawals I think that there may have been some of his ejaculate inside of me, but I didn't think much of it because I was told the Depo injection is one of the most reliable forms of birth controls & even more effective than the pill I had previously been on. We then had intercourse again on July 4th. While I know it may have been too early I took pregnancy tests approximately 2 and 3 weeks after intercourse on the 25th. Both came up negative, however I legitimately feel pregnant. My breasts have seemed to grow a bit, I'm nauseous nearly constantly, have a ton of brown/pink/clear/blood-tinged spotting almost every day, headaches, my smell triggers everything, & tons of cramps. However I did not get my period as I was supposed to at the beginning of the month. I'm planning on taking another test, but I would just like to know some opinions on whether or not I might be pregnant. I am deeply afraid of pregnancy & even have nightmares about it, so I'm not sure if my anxiety is making these symptoms worse, but I can't get them to go away. Any help at all would be greatly appreciated, thank you :(
