I'm scared I'm pregnant .. I didn't wait 7 days after taking the depo injection I only waited 2 days and my boyfriend ejjaculated in me and I didn't take emergency contraception .. Do you think 2 days would of been safe enough or is it compulsory that you wait the 7 days ? I'm feeling nauseous and I don't no if this could be because of the depo injection or if I'm pregnant .. I've done 2 pregnancy tests and they have come back negative but however it's still early stages and I'm not sure if it would detect or not .. It's only been 2 weeks ..
