The start of my last period was April 3. My ovulation day was April 16th. I have been experiencing pelvic pressure and frequent urination for about a week now. I had unprotected sex all around my ovulation day. I am planning on going to the Dr. tomorrow but wanted to get prepared. I have never felt pressure like this before and am starting to get concerned. Could I possibly be pregnant?

Yes, you could possibly be pregnant.

Are you? There's no way for us to know that.

I am going to the Dr. tomorrow to find out what the cause is. I have no other symptoms of pregnancy so that is what confuses me.

Every one has different signs of pregnancy, some do not show as much as others.

The only sign of pregnancy that matters, is a missed period.

Symptoms don't matter, they can be attributed to numerous other things. For that matter, so can a missed period.

But a missed period is the first symptom of possible pregnancy, and taking a pregnancy test is the only way to confirm. We can't even give you an educated guess, we can only say that you had sex, so pregnancy is possible. The rest is up to you to figure out.

Good luck.
