Pregnancy or pre-menstrual symptoms?

1. I had my last period February 28th.
2. My calendar says that my period is usually 26 days apart, which means the next one will fall on March 25th. So!
3. Around 9 days after my period, I had unprotected sex, he pulled out.
4. About 16 days after my period, so 7 days after having sex, my boobs got hard, I got ovulation like cramping and my usual white stringy vaginal discharge.
5. My periods are "due" in 9 days.

Did what I just explain sounds like I'm having symptoms leading up to my period?
I heard that stringy white vaginal discharge is fertile discharge that tells me that I'm ovulating. Is that true?
Can stressing worsen my pre-mens symptoms?

THANKS A BUNCH!

if you have any of these symptoms right now:
You may feel nausea or queasiness. Some women vomit. ("Morning sickness" can happen any time of day -- it may help to eat small meals throughout the day, snack on crackers or toast, or drink juice or lemonade.)
Your breasts swell and may be tender.
Your nipples and the area around the nipples (areola) get darker and broader.
You have to urinate more often.
You feel tired.
You may become constipated and have heartburn (Tums may help).
You may have headaches.
You experience mood swings -- feel angry, sad, or happy for no reason.

Then you might be pregnant but it's hard to say because you need to wait to see if your period starts on the 25th if the your period hasn't come at all after that day. i suggest you use a pregnancy test

Oy Mazel tov! Am I invited to the bris??

It's difficult to say. Every time I've been pregnant, I've always felt like my period was coming (cramping, sore breasts, fatigue, low backache, etc.), but it never came.

Stress certainly aplifies your feelings. You are just going to have to wait. And, for the future, everyone I know who had an unplanned pregnancy (myself included) used withdrawl. It doesn't work at all. Get some birth control.
