hi TS,
Yup, go for a medical checkup confirm if your gf is really pregnant or not.You are under a lot of pressure. I am not in you shoes and cannot imagine the stress you are in.

I am not sure if you are close to your gf family but i think its best you should discuss with your gf and decide if you would like to inform your family and her family about it.

Regardless of the situation, if performing an abortion is your next step, there are inherent risk involved.You need their support now than later if complications arise.

Sure enough, you will get an earful maybe more but you seem responsible not to breakup with your gf now or pretend its not you who is the father. So perhaps you should admit to both families.

A suggestions is to get both of you registered to show your intent to be together and get the family support during this difficult period.Its best to have 2 families or at least one taking care of you and your gf at this time.

They may offer advice, financial and moral support which we may not be able to offer in the same amount.

god bless...

unfortunately no matter what we say, we can only pray for you but cant be there for you.
