So I was a very silly girl at 1am this morning (overtired too) and checked my cervix for the first time since somewhere around 6-7wks which was the last time I checked it (I've always been curious about the changes that happen to the cervix during pregnancy lol but haven't checked it since then due to starting to loose bits of plug from 9wks, apparently cervix was still closed at an emergency scan due to pain and slight spotting at 17wks 5d), and it felt very soft, open and grainy for the 2cm of it I could feel, like having a gravel rash on some part of your body is the only way I can describe it.
On wednesday last week we were down the street and in the space of around 6 minutes I had 3 pretty strong contractions that had me doubled over for about 30 seconds each time (I have an irritable uterus so it isn't uncommon for me to get them every 15 minutes or so on a bad day), anyway I haven't had any contractions since but right after these contractions I went to the toilet and had *TMI* a huge 50 cent piece sized glob of mucous that looked like plug, when we got home I went to the toilet again and had another big piece of mucous, since then bub has been feeling like it's really low (right behind my pubic bone nowinstead of just below my belly button like it was before these 3 contractions), I've been getting stinging pains through my cervix and vagina, it feels like bub is sitting right on or in my cervix when it moves (I can feel the fiddling of hands/arms/head right down in there and kicks are now right inside my left hip most of the time) and I've been losing clear and thick yellow mucous, there's no smell though, peeing a lot more than normal and sometimes I don't even feel like I have to pee on the toilet and it trickles a bit, yet my undies/pad aren't wet.

I have my 20wk scan tomorrow morning so I'll ask the sonographer to check my cervix then, but I was wondering if I should be worried about all this?

My cervix had been normal, slightly open (as usually happens after multiple births/pregnancies) with no bumps/pebbly feeling last time I checked or even when I went back to charting to prevent pregnancy about 3 months after DD was born.

Sorry if this is a bit all over the place but I've been a bit stressed about it today especially with all the really low movements and stinging pains recently.
Someone tell me I'm just being silly please I don't see my OB until March 2nd either.
