IUD & Depo shot

Vanessa

So i went to get my iud out but since I had sex in the last week she said she wanted to wait because there’s a high chance I could get pregnant and so she put me on the depo shot and I’m supposed to come in and get the iud out within 10 weeks, this was about 2 weeks ago, but I’m a week late for my period and my boyfriend has came in me a couple times... should I be nervous or do you think it’s the birth control?
