Am I pregnant? Whats going on?

Me and Bf had unprotected sex on Feb. 4 (day of ovulation) .. around Feb. 7 & 8 I started feeling queasy when I woke up and had bad constipation .. & cramps .. & very tired .. then my "period" came Feb.9 .. BUT its 9days early ?! Could something be wrong ? My period is never off or early .. I'm confused !
- it wasn't heavy bleeding .. it was light .. but it wasn't like period blood .. it was more of a brownish color ..
- I don't think it was morning sickness .. it was just like a queasy stomach ..
- & the "period" only lasted a day and a half , and wasnt heavy
- I use the bathroom quite frequently now

I am no expert on those things but you should know that when you have unprotected sex, it does not matter when you have it. You will always be at risk of getting pregnant. At certain times the risk will increase or decrease, but it is always there. Never have unprotected sex at any time unless you plan to have a baby.

Take a pregnancy test. Then address the symptoms according to the result.
