Okay so, question. I had my period March 28th, it's usually 6 days since after my first birth. Mid way into my cycle I had made love to my fiancé. (somewhat trying, somewhat not) and we made it off and on in April. I didn't realize I was late until last Sunday. I was 20 days late, now 25. I took a pregnancy test because I kind of did feel like I did with my first. Came out to be a verrrryyyy faint positive, could barely see it. Yesterday I took another one and it was invalid. Shouldn't I already gotten a good positive response the first time since I was 20 days late?
