Hi China,
Did you expect your period to start on Monday?
If so, it is VERY unlikely that you are pregnant. The timing is poor. It's also too early to test, you'd need to wait at least 2, preferably 3, weeks after having sex. It's also very early for any symptoms.
Day 1 of your cycle is when your period starts. You normally will ovulate sometime between days 11 and 16 of your cycle. You had sex on/about day 26. The egg is only viable (able to be fertilized) for about 48 hours after ovulation. So, by about day 18 of your cycle it can't be fertilized and you won't get pregnant.
There's always a chance however.
I don't think you are pregnant.
