Is there a chance I could be pregnant.

ok I'm so confused because I don't keep track of my periods. But I always come on around the 1st of every month mostly a day or two after. So the 1st came and i new i was due on any day and then nothing.

I remember that from the 15th to the 21st of April me and my boyfriend were on holiday and liturally went sex mad lol! But always used a condom apart from the silly once or twice we used the pull out method which i know is stupid and we never did it before.

In April I came on, on the 3rd so if i work it out i should of come on the 2nd or around there. But i know as I'm always random and can range from the 1st to the 3rd of every month. But as i'm never normally late i got worried on monday 5th and took a test.

Negative!!! Whoo i calmed down not pregnant. But then by the 8th the thursday I still had not come on so I took another test.

Negative! cool there is no way I'm pregnant now and as its only the 10th two days after i took the test theres nothing to worry about. I don't have any symptons maybe a bit of tiredness but thats it oh and Ive been extremly moody but again could be anything. And I've gone of food a little but its been such hot weather these last few days that it could be just down to that. This is the UK hot weather is not normal. So theres no possible way I am pregnant right?

I'm not sure if I'm 10 days late, 8 days late or 4 days late. But as I said 2 negatives is a no for sure.

I guess I just need someone to reasure me theres no way I'm pregnant. Sorry if this is the wrong group to post this in I was not sure. Thanks x
