I had sex with two different men 10 days apart, my last period started on the 7th of June and lasted until the 26th of June which is unusual but because I came off birth control it could of been that, anyhow I had sex with guy #1 on the 1st of July and then I had sex with guy #2 on the 10th of July. I'm struggling to determine when I conceived due to my last period being 3 weeks long when is usually 5 days long, my clear Blue test says I am 1-2 weeks pregnant
