Ok, age matters here. If she was 17 or 18 I would have sympathy for the whole small town thing, I was a small town girl that got myself into a lot of reputation ruining situations. However the OP is almost 30 that's old enough to understand and want to ignore small town gossip and to get over this high school stuff. I mean I didn't see the age of this person and assumed that she was in her late teens by this story.

If I were 30 still living in my small town where I graduated with 60 kids and some man's mother was calling me hoping for me to be sterile and putting a pox on me I would be fury as that type of entitlement and I would block numbers and screw every one in the town and live my life. I see the people I graduated that still live in our town who are in their 40's dealing with the same high school nonsense and it blows my mind that they would still be at it. Like why? Why at 30 or 40 would you let a town or even a small circle of idiots ruin who you are.

Op needs to make a decision about her pregnancy and leave all of these people in the wind, and it's as easy as it sound.
