too early for symptoms?

[sxycat]

I had my last period may 29 then had sex June 8. (Mid cycle for me). I am on the pill but had been on antibiotics for a week which I have heard lessen its
effectiveness.
Anyway this weekend I started having very sore breasts...nipples are very tender...and period isn't due for nearly two weeks...this app says if I am I'm three weeks pregnant? Could symptoms show so early?  I'm also exhausted and some but not constant  backache.

June 8 was my mid cycle and I'm not due for another week as of now...to clarify what I meant was I was getting symptoms this weekend from Fri... almost two weeks before period is due so I was wondering if it was possible to be getting symptoms as early as a week after conception because almost two weeks before period is way to early for me to have pms symptoms.
Come to think of it I was peeing a lot this weekend too! Thanks so much for response.

How can June8 be your mid.cycle but not have period due for 2 more weeks from today. However sperm can resided in your body for up too a week . And u can start showing.symptoms early i was tired an peeing all the time the week after conception and did a test it was negative then did another a week later and positive.
