So my boyfriend and I have unprotected sex all the time (we want to have kids) and my period is 7 days late I've taken 3 tests and they all came back negative the last time I was pregnant was a year ago and I had a miscarriage but when I was pregnant that time it barely showed up on pee tests as well I had to go to a doctor to get a blood test to confirm. Should I go to a doctor again or keep on taking pee tests and waiting? Also I mean I've felt nauseous some times but never actually threw up before and I have some spouts of having to use the bathroom a lot when I haven't drank a whole lot would that mean anything as well?
