Question for you all!

My husband and I have sort of been trying for a baby lol but not really😂 we want one. But just haven’t been using protection. (So basically not preventing it but also not trying) He is in the military and I went to visit him in Tech school. The day that I saw him was on the 26. I hope this is not TMI😂 but- every day and every time we had sex, from the 26th-31st, we didn’t use protection. My fertile window was on the 29-4th. I went home on the 1st. Do you all know if there’s a chance I may get pregnant? And when should I take a test? I got a little too excited and checked today and yesterday but I think that I may have checked too soon because they were negative. Help please!!

Thanks :))
