So many things wrong...2 periods since Nov and now missed this month!

Weird one I know but me and the other half last has sex on the november fertile days ( I've not been well at all since so hence the dry patch 😂 so had a little break with ttc) and had 2 periods at end of Nov and end of December and this month nothing. I've been feeling weird twinges in my belly and I've been constipated for the last week and half. I feel stodgy and just not nice in general. I've also had very sore boobs ( I'm lucky and never get sore boobs during the time of the month) so that threw me off a bit. I've also been getting an egg white mucus when I go to the toilet (sorry tmi). I've done a test but nothing. I should also point out I have pcos and a prolactinoma. I know I probably won't be pregnant but has anyone else had this? ( I am always like clock work with the date of my periods too? Any ideas ladies? Thanks x
