I had sex on Dec 19th, my boyfriend came in me BUT it was his third time that day along with him having a low sperm count. My period was suppose to come Jan 6th & from online Calenders I ovulated Dec 22nd but around that time I was so dry to the point sex was hurting us both on Dec 19th so anyways I'm now a week late and I've been under stress along with a new job and all. I test Jan 14th at night and the test came back negative so fast it wasn't even funny. The brand I'm using is clear blue and they say you should test a week after your missed period SO I DID. Today Jan 16th I tested this morning, the first morning pee and that again too was negative. I don't get it. Why am I late ? The only symptoms I have are I feel bloated.. Any idea? These test are 99% right. There's just no way I don't feel pregnant.
