Neg test

So I have all of the symptoms of pregnancy. Nausea sore breasts everything like that. I was on birth control at the time me and my husband had sex but was on the sugar pills and I missed a couple of days on the new pack. I thought I got a positive test last Sunday 1/31 but ever since all my tests have been negative. I was 4 weeks at the time of the “positive test” I am 5 weeks now if I’m pregnant. When I got the “positive” result I immediately stopped taking my birth control. So it’s been about a week and a half now and would have normally started my period but I haven’t. Normally would have started last week sometime a couple of days after I stopped taking it.

What do you ladies think about my situation?
