Single mom by choice.

So I'm 28, 29 this year. Been single for bout 6 years. And my past relationships, the guys didnt want kids or already had them and didnt want anymore. This is kind of a sensitive topic for me but I've been wanting advice. I've been wanting to be a mom for some years now, and I've been thinking of being a mom by choice. Well, I'm still unsure of that, cause I'm not sure of how it would affect my love life having a baby by doner. Any tips and advice? And any moms by choice on here could probably let me know on what made you a single mom by choice? Thanks itll help alot.
