Is my gf pregnant? ASAP ASAP

My girlfriend is 21 years old and has been on Yasmine since she was in middle school. Over the past three weeks she has irregularly taken her BC pill. She took two weeks worth in three weeks and took the pill at random (Random day and random time of day).  She has NEVER done this with her birth control, usually consistent on taking it every day. Starting around 3 weeks ago, we had unprotected sex in which I ejaculated inside of her. She was having no signs of anything until now. Could she be pregnant or is this a reaction to her irregular birth control use? ASAP ASAP

Symptoms
- tender and erect nipples
- constipation
- a little dizzyness
- rapid weight loss (7 pounds in one week)
-headaches (earlier symptom that has now gone away)

Please let me know asap

These symptoms are recent and just started up, not consistent during the three weeks. She also says she doesnt "feel pregnant"

You just have to wait and see if she misses her period then take a pregnancy test..because you don't really get any symptoms of pregnancy that early

First of all, she should see her doctor about a BC overdose!! You're never supposed to take more than 2 to catch up, so two weeks worth in two days is so bad! Second, that is really going to mess up her cycles, really, so any symptoms she's experiencing could be from the change in hormones, however, if you're having unprotected sex while missing multiple BC pills, there's a chance for pregnancy. If she's not going to take the proper steps to make sure shes protected, you really need to use condoms. Good luck!
