8 weeks pp...possibly pregnant..

So, I had my daughter 8/24 and at 3 weeks pp SO and I had unprotected sex, he pulled out but slid back in after cumming. Then at 5 weeks pp the same thing again. And at 6 weeks he came on but not in my vagina. The rest of the times we've had sex since then we finish with BJ.

I had my postpartum appt last Monday and they tested me and it was negative, and I go back tomorrow for another test before they insert nexplanon...I'm so scared.

We should have been more careful. I dont want anymore babies. I've always wanted ONE baby and I have a gut feeling that I'm pregnant...

Anyone else 8 weeks pp or later and still no period??

Also, I'm not nursing.
