Firstly please don't judge as I did use birth control.
I had sex with my ex on May 6th 2012. He gave me chlamydia. I was treated on 23rd May where they took a pregnancy test & told me I was not pregnant.
I began having sex with my current boyfriend on May 14th & have only been with him since. He was tested for chlamydia & given the all clear.
On 9th June I took a HPT after not coming on my period which is normally at the end of the month but can be irregular. It had a faint line I took another one which also had a faint line. So far I've had 4 ultrasounds. 1 on 19th June where just a ges sac was seen, 26th just a yolk sac. 8th July heartbeat seen & due date predicted 21/2/2013. 17th July due date predicted 23/2/2013 & 14th Aug predicted 19/2/2013.
All facts so far lead towards my boyfriend but can I safely eliminate my ex without taking a DNA? I don't want to give my boyf any unnecessary doubts he is really supportive and happy.
