Hi i need some major advice.Me and my partner broke up with eachother for a few weeks in late november. On the 3rd of december i stupidly slept with somebody else (one night stand, too emotional and hurting). Today i have had 2 very positive pregnancy tests. Im unsure of when i conceived and im worried i conceived on the 3rd of december with this ONS. I have irregular periods as i have pcos and i had my first baby 18 months ago, my last period was on the 29th of october. Im just so worried this baby isnt my partners. I know its my stupid descision but can anybody help? If i conceived less than 3 weeks ago can my tests be this strong realistically? Can anyone help?
