First Pregnancy & i honestly don't know what to expect lol

I'm having severe period like cramps and pressure on my ass, idk what is that about, & ALOT Of pressure down on my cervix. I don't want to go to the hospital and they send my ass right back home😩

I have a Apt in the Morning so I'm thinking i should just wait till then, i wanted my doctor to then sweep my membrane if I'm not dilated but idk i feel like i am. Some advise will be helpful Bc now I'm starting g to feel a bit depressed 😣😒☹️
