Lawmakers in the Republican-led House are looking at measures that would criminalize abortion, prohibit late-term abortions and remove restrictions on picketing outside of abortion clinics.
New Hampshire's among the least restrictive states when it comes to abortion.
A group of anti-abortion bills heard last year didn't pass the Legislature, then led by Democrats.
One would establish criminal penalties for people who perform abortions to "terminate the life of a viable fetus," except when there's a danger to the mother's health.
Another would prohibit abortions if the gestational age of the fetus is at least 24 weeks, unless there's a medical emergency.
Opponents say the bills could have severe impacts on women's health care and doctors.
