Okay, so I've been on the depo shot for 4 months. I got my last depo shot on April. Well I had sex like 2 weeks ago, he came in me twice. Now I'm having all these pregnancy symptoms for the past couple days like cramping, being gassy, belching, bloating, and I have a yeast infection. I've had unprotected a lot while on the depo and haven't had these symptoms until now. Could I be pregnant?
