I'm 13 weeks pregnant and so excited! But there is 2 possible fathers. Each being an ex partner. On my 12 week scan I counted back to the 1st of December... I had sex with potential father 1 all way through November last time being the 28th.. Then had a light period starting on the 30th ending on the 3rd of December. I had sex with potential father 2 on the 8th of December roughly. Does this mean it has more chance to be potentially father number 1s?!
