Bad friend?

I'm 20, and I'm 28 weeks pregnant. My best friend is 21, recently got her license, and her grandmother bought her a car. My car is out of service currently (😧). Friend used to live a couple of towns over (her mom's), about 40 miles, but suddenly moved to her dad's, an additional 20 or so miles away. So, 60 miles. She calls me the other day and says "My mom is out of town, I'm going to house sit. I'm gonna come pick you up, and we're going to go back to my mom's. My (guy friend) Cam is going to come over, and I want you two to meet. The 3 of us are going to spend Friday and Saturday night there. It's not a question."

Now, she's not someone that takes "no" very easily. at 7 months pregnant, I don't really want to be sleeping anywhere but my own bed. Not to mention I know she and her friend are going to want to drink, are chain smokers, and my friend loves to walk around the town late at night. I don't really want to walk up and down the streets of a less than reputable town at midnight-2 am ( shadows of metro ATL) I can barley handle the flight of stairs at home in the daylight. Plus, i dont want to be stranded and having to rely on someone else to get home, espescially if she might be drinking, or being trapped in a car with cigarette/weed smoke. I try to explain this to her, but she isn't hearing it. She doesn't have my address (since I've moved in with boyfriend), but she is aware that it's not too far from my parents' home.

The only way to say no is to not answer when she calls, because it's very common for her to bully me into doing things. So Friday, the night that she wants to pick me up, I put my phone on silent and go clean the kitchen and work with boyfriend in his workshop. we don't come inside until after 9. Ihave a few missed calls. then I don't hear from her all day Saturday, but I see on her social media that sure enough, she and group of people are out on the town, more than just this one friend she wanted me to meet. Sunday, she starts blowing up my phone- in a period of about an hour, I have more than 40 texts, and about a dozen missed calls. she wants to come over to my house. normally, I would have no problem with this. however, last year, I lived about 30 minutes away, and she would come over to my apartment. she never showed any regard for respecting my home, had a habit of going through my kitchen and opening everything "to taste" it, and then would complain that she didn't like it. She would beg me to let her spend the night, but then at 2 am, decide that she's homesick and want me to drive her home. So I'd be stuck driving 30 minutes to drop her off, then another 30n minutes just to get home, without even so much as a thank you or gas money. she consistently left my apartment in tatters, and never picked up after herself. so when boyfriend and I moved in together later in the fall, I had no problem not giving her the address. now, we are in the process of remodeling, and with the baby coming, I just don't feel up to playing babysitter. And unfortunately, having her own transportation, she has made it very clear that she expects an open door policy, and wants to be able to show up at my door whenever is convenient for her, regardless of my plans or work. and honestly, I'm tired of hearing her criticize me for my preparation for my child, and that I'm not preparing the way she wants me to. Now I'm just venting. but am I wrong for not wanting to be around her a whole lot, and for not giving her my address? am I a bad friend for avoiding her? am I out of line?
