I had sex while I was firtle (according to my period planner.) then I had sex the first day I was ovulating. Is there any chance in pregnant? Are there any early signs? I've had a little bit of whitish clear discharge and my pee is a dark yellow with a reddish tint. Help!!

Did you have unprotected sex? If yes, then yes you could be pregnant.
There is always a chance of becoming pregnant with unprotected sex.

While it's not possible to tell without a definitive pregnancy test or a missed period, there are some early pregnancy symptoms that some women notice including:
Headaches, tender breasts, backaches particularly in the lower back, bloating, morning sickness, and discharge similar to that which you described.

Just because you have one of these symptoms does not mean 100% that you are pregnant. But, if you are very worried that you may be I would suggest a home pregnancy test but depending when this all happened you may have to wait a bit for it to be accurate because HcG levels take time to build up.

Now that I'm thinking about it you could also have a UTI or bladder infection which would change the color of your urine and the discharge. If you go to the doctor (which if you want an official pregnancy test you'll have to do) they can give you antibiotics to clear it up.

Another thing... I woke up during the night to heart burn really bad when I would lay on my right side and it would feel like I was going to puke until I sat up for a few minutes then laid back down only on my back. The heartburn went away slowly along with the pukey feeling . Is that just a weird thing that happened? Or is that a pregnancy symptom?

I was firtle the first of aug. until the sixth. I had sex on the second. On the fourth I was ovulating and had sex on that day... I'm suppose to get my period on the 18th.
