I'm so scared.. could I be pregnant again??

Shartay

I kind feel like I might be pregnant again and I'm so terrified to take a test.. I just had a baby and she is almost 7 months old. I couldn't do it with a second child.. I'm so scared. My hubby and i had intercourse the beginning of January just a few days before I got the iud. I had taken a plan b before I got it inserted. a month later when I went for a check up on my iud and I had gotten a vaginal ultrasound to make sure everything was okay. I didn't see anything but would you have been able yo see anything?? serious question!! I was feeling nauseous at the beginning, never got sick over food or anything but I had been getting lots of headaches too. Idk now I swear I feel kicks but it's not like an everyday thing. it's like every two to three days. But i can't tell if it's a kick.. I don't look pregnant?? but the "kicks" are tripping me out!! do you think I could be pregnant again?! I'm scared to take a test..
