could I really be pregnant this time?!?!?!? just trying to get some opinions before I take a test thank you all in advance?

I haven't gotten my period in over a month and a half, and have been taking prenatal vitamins for about twoish weeks now in order to hopefully help. a couple days ago I had some slight spotting, then nothing else, and since then my CM has been like watery/creamy. The smell of certain foods makes me so nauseous, and I find myself getting hot flashes, and craving greasy foods. I have also been soo moody and emotional and have gotten acne between my eyebrows, and near my nose and chin. And also I have been getting pelvic pains/soreness that I have never had before.people have told me that i look like i have lost weight when i feel disgusting. . I don't know if that means anything but figured id throw that out there. my fiancé and I have been trying to conceive for about a year now and haven't had any luck.. I have gone two to three months without a period and had ll the symptoms then took the test, got negative, and started right after so im a little hesitant to take a test, because I go into a depression state for like a week. did these things happen to anyone? or sound like I could be? I know the only way that I will truly know is if I go and take a test but just trying to get a little bit more advice.. thank you all so much in advance! hopefully this year brings us good news ! Good luck to everyone else trying to conceive as well!!!!
