Stephanie Abrego pleaded guilty to an indictment charging her with conspiracy to possess with intent to distribute more than 50 kilograms of marijuana. Abrego was sentenced at the bottom of the guideline imprisonment range to a 33-month term of imprisonment and to a three-year period of supervised release. She was ordered to pay a $1,000 fine. Abrego gave timely notice of her appeal.

Abrego contends that her sentence should be vacated because it was imposed pursuant to an unconstitutional mandatory guidelines system, contrary to United States v. Booker, 543 U.S. 220,---, 125 S.Ct. 738, 768-69, 160 L.Ed.2d 621 (2005), a so-called Fanfan error. See United States v. Martinez-Lugo, 411 F.3d 597, 600 (5th Cir. 2005), cert. denied, — U.S. —, 126 S.Ct. 464, — L.Ed.2d-(2005) (No. 05-6242). This court’s review is for plain error. See id.; United States v. Mares, 402 F.3d 511, 520-21 (5th Cir.), cert. denied, — U.S.-, 126 S.Ct. 43, — L.Ed.2d-(2005).

Abrego cannot carry her burden of showing that the Fanfan error affected *293 her sentence. See Martinez-Lugo, 411 F.3d at 600. There is nothing in the record to suggest that the district court felt constrained by the mandatory guidelines in imposing Abrego’s sentence. See Mares, 402 F.3d at 522; see also United States v. Bringier, 405 F.3d 310, 317 n. 4 (5th Cir.) (minimum guideline sentence, without more, insufficient to carry third prong of plain-error test), cert. denied, — U.S. -, 126 S.Ct. 264, — L.Ed.2d - (2005). The judgment is AFFIRMED.
