So two months ago I had a chemical pregnancy. According to this app I was supposed to get my period sat so that makes it 4 or 5 days late. I took 2 88 cent test from Walmart and a positive line didn't show up until a couple mins and is very faint. I don't want to get too excited, today I have spurts where I feel like my period is coming any second, go to bathroom and nothing and then I get nausea feeling .. hmm ideas ?
