Confused and Irritated

I have a suspicion that I may be pregnant. I absolutely hate the fact that almost all pregnancy symptoms are similar to menstrual symptoms.

Symptoms: Extremely sore nipples (to any type of friction/touch) | Bloating | Nausea | Craving food (especially salty foods) | Food Aversions | Diarrhea | Severe Mood swings | Headaches | Lower back pain | Side Abdomen pain/cramping (both sides - feels like I'm being stabbed/squeezed)

Problem: I just got off of a 3 year birth control and haven't had a period since I started the bc. So, I have no clue when to take a pregnancy test. I called my gyno and she said to wait 6-7 weeks? That's outrageous and I know I probably shouldn't wait that long.

I've had sex without a condom for about 3 or 4 weeks now and have only been using the pull out method (I know, I know - it's not a wise decision).

Honestly, I don't know what to do. I want to take a pregnancy test this weekend, but I don't know if it'll be too early? I did go to the hospital about a week ago for other reasons and they did a pee test that came back negative.
