What do you ladies think?

So yesterday I was exactly 36 weeks pregnant. I have an almost 2 year old so I'm pretty busy through the day. I didn't notice little man kicking and moving as much after my daughter went to bed. I decided to get in the tub, since that usually gets him moving. Nothing really happened, just some slightly consistent braxton hicks. I get out and try a glass of cold pop and a cookie. Still nothing. I tried talking to him and poking him. Nothing. Then I ate 3 small freezies and about a half hour later he was moving like usual. So I didn't think anything of it after that. Later that evening my husband and I had sex, and I had multiple orgasms which made me have more slightly consistent braxton kicks. I didn't think anything of it because I always usually have braxton hicks after sex. Anyways, today everything felt usual. Lots of movement and no braxton hicks. (Tmi coming up!) Around 4pm I went to pee, I wiped and there was a large mucus blob. Possibly my plug? Ever since last night I've noticed I've been having crampy bowel movements and wetter panties from increased discharge. My breasts have been more sensitive and leaky since I woke up today.

I'm probably just looking too far into my symptoms, but I never went in labor with my daughter so dont know what to expect or look for. My next appointment is tomorrow so I'm going to tell my doctor about it, but curious what other women think.

Also when do they start checking cervix in your area?
