Will birth control affect me differently me after having a baby?

Uh let me explain some back story. I have been on EVERY birth control known to man kind. I had a really crappy gynecologist and I don't feel sorry saying that. She talked me into staying on birth control that made me puke up my food for 4 months straight, telling me "give your body time to adjust."

I bled for 5 months on the depo shot "give your body time to adjust."

I hit adulthood and I realized I had a lot more control over this than I thought. Like I started birth control in my teens and my mom really didn't help with what was going on just listened to the doctor. I'm sorry but they're not always right.

I used the FAM method for like 5 years, but my periods started becoming so irregular I had no idea wtf was going on anymore. So I searched for a well respected gynecologist and I still drive 45 mins there and back to see him. HE took the time to look at my history with every birth control, and suggested the IUD. The IUD Always scared me to death. But he took the time to put one in my hand, talk to me about it, be honest, and he told me "if you try the IUD and you don't like it, all you have to do is call me. I will never force a patient to stay on a birth control when they come and say it has bad side effects and I don't care how long youre on it. If you get it, and call me a day later to remove it, I will.

So he gave me a week to think on it and I came in and got it. Insertion was traumatic, but 100% worth it. I love this IUD, I literally have zero issues with it and dont even feel like I'm on any birth control. I told my doctor he's the birth control match maker.

I'm 25 and want a baby soon. I am so worried that I'm gonna have this IUD removed, have a baby, but it's gonna change my body and my hormones and I'm never gonna be able to use the IUD again. It is THE ONLY birth control my body accepts and lives peacefully with.

I don't want to have a bunch of babies close together. I also don't want to have one baby and tie my tubes and call it a day. I want to have the freedom to plan my babies as I want and I'm so scared that having a baby will change my hormones so much.

I forgot to mention I had to atop using the FAM method because I have PCOS and THATS why I stopped fam and searched for a good OBGYN because I didn't want a baby but couldn't

Figure out why I wasn't having periods or ovulating twice in one month like that shit was wild. I'm on metformin now and have a period every month with the IUD

I'm telling y'all right now, preventing pregnancy has been a pain in my ass all my life and if I have a baby and cant handle the IUD anymore I'll cry my eyeballs out. This is the best birth control for me and im so lucky I finally found one that doesn't make my life miserable
