Okay I had sex on the day my period ended last month and he used a condom and also pulled out with the condom on. This month I was sick and I went on a really strict diet and lost weight pretty fast but ended up gaining it all back and haven't been eating healthy at all...and I've been worrying about being pregnant like crazy... I took a first response pregnancy test on the 7th day my period was late and it came back negative... I am waiting to take another one when I am 10 days late... Do you think I am not pregnant if the 10 days late one is negative too? Is it possible I'm just really late or not getting a period this month?
