There is literally a Plan B. Known as the Morning After Pill. Where the pharmacies in TX likely don't even stock it- Planned parenthood will. It also will NOT fall under the 6 week rule. In case of rape or incest- this may be the best option........
You can buy levonorgestrel morning-after pills (like Plan B One-Step, Take Action, My Way, Option 2, Preventeza, AfterPill, My Choice, Aftera, and EContra) over the counter without a prescription at drugstores and pharmacies. It doesn't matter how old you are and it doesn't matter what your gender is.
You may be able to get the morning-after pill for free or low cost from a Planned Parenthood health center, your local health department, or another family planning clinic. Call your nearest Planned Parenthood to see if they can help you get emergency contraception that fits your budget.
