Okay, so I'm currently taking tri-sprintec and I had unprotected sex with my fiancé on Friday night, and again on Sunday night. Both times, we used the withdrawal method, and he never actually ejaculated. It is now Tuesday and I'm on my white pills now, I started them Sunday, as usual, but it's now Tuesday and I still haven't gotten my period. I'm afraid I might be pregnant. I haven't been eating the healthiest for the past month though and I feel that could have something to do with it. I usually always have it by now. What do you think?

It's a remote possibility... and you really do want to know if you suspect you are... try taking a HPT to find out.
