I had unprotected sex with a guy and a few weeks later I started feeling the early symptoms of pregnancy(I already have 4 children) so I know that feeling well. So a few days before my period was due I took several 6 day sooner early pregnancy tests which all showed positive, then 2 days after my period was supposed to start I started, although there were no clots or clumps and I always have clots or clumps when I'm on my period. Well I still feel pregnant so I took another early pregnancy test last night and it was positive. But then I took a regular urine test like the ones used at health departments and it was negative. What could be going on bc If I'm pregnant my hcg levels should be high enough to show on a urine test because if I am I'm estimating that I would be 7 weeks pregnant
