Please help me: lower right abdominal pain

[chestnut61]

So on Friday evening I was driving home and got a sudden wave of pain on my extremely lower right side, near my vagina. The pain was like being stabbed, it then began to feel like i drank poison, like this nasty feeling going down my throat to stomach. It subsided after an hour. The next day there was slight discomfort but totally bareable...I felt perfectly fine. However a few hours ago it came back but worse. And this time my whole stomach felt like I was being stabbed, and had cramps. I had sex so I’m sure it irritated whatever it was. I went to urgent care yesterday morning and they said it was just pain from ovulation...my stomach is bloated I look like I’m pregnant. I’m not constipated—I went yesterday morning.  I’ve been more gassy than normal but other than that I don’t have a ton of symptoms. Just bloating, and lower right abdominal pain. Could this be my appendix? I really don’t want to pay for an ER visit? If it is could I wait a few days until I can get an appointment?
