Who thinks I should get in touch with my birth mother?

I am a 15 years old girl and I need some advice.my birth mother left me in hospital immediately after I was born and didn’t even want to see me.she was a student of my grandmother,who was a teacher,by the time she got pregnant.she didn’t tell her parents what was going on and by the time they realized it,it was to late for an abortion.she was 18 years old when she gave birth to me,still in high school and she had problems at school because of her situation,wasn’t able to learn properly that year and scored really low on her exams and probably didn’t go to a good university,even though she was a good student.her boyfriend,my birth father,broke up with her and left her alone without looking back.when I was 6 months old,I was adopted by a lovely couple,who raised me and offered me all the love and affection I needed.they are both very well known doctors in our town and frankly I have a really wonderful life,I have everything that I could dream of and they give me a lot of freedom.the mother of my adoptive father,my grandma,was the teacher of my birth mother.my bio mom knows my full name and where I live and who is my adoptive family.in fact,when I was little,there was always a lady following me and my adoptive mother when we were together in the park.she followed us several days,no matter where we were going.my mother suspects that lady is friend with my bio family and they asked her to follow us to see how I am doing.my dad told me there might come a day when mu bio mom might try to meet me.she lives quite close to my town,in a village and I think she’s married with a priest and is a biology teacher.she might have been pregnant last year,but dunno for sure.I was wondering,would it even be worth contacting her?I thought she left me,because she didn’t want me at all and might want nothing to do with me.and I thought if she’ll have another child,then I doubt she’ll want to get in touch with me.what do you think?what should I do?should I try to contact her?
