Can’t tell if I’m pregnant...?

I had sex with a condom & he pulled out on Feb 7th.

According to the calendar I’m late by 2 days.

Technically it hasn’t even been 3 weeks since I’ve had sex.

I have had 3 negative pregnancy tests. Though I’m sure if I should keep taking them....

I was emotional this morning due to other life stresses though it could be a sin that I am starting my period soon....?

My question is are there any other significant signs that show that I could be pregnant?

Breasts are tender but not firm...?
