Well, now you need to figure out what you want to do. It is best to make this decision assuming he will not be involved. Are you able, financially, emotionally, and logistically, able to raise a child by yourself? If not, are you willing and able to go through a pregnancy to give the baby to an adoptive family? Then there is always abortion, for some women who do not wish to be pregnant this is a good option.
Think over your options before you talk to him. There are so many posters on these forums who's children's fathers promised to be there are no support them amended never followed through. Do what is best for YOU.
Well, the tests came out positive...
Until you take a test there's no need to worry. Hope all goes well
Take the test first just to be 100% sure then just call him and ask to talk to him in person and tell him. If you go to a pregnancy clinic they can give you proof of pregnancy just incase he needs more assurance. I hope all goes well for you hun
