Advice please 💕

I had stopped my combined pill 6th Dec a week or so later when I wiped it was light pink then next day a rust kind of colour then nothing since. Me and my partner have been DTD near enough everyday since coming off pill. I still haven't had breakthrough or period and not sure if I've ovulate either. I've had some nausea a little and my breasts are pretty sore and alot of cramping on and off with a few little flutters/twinges also bloating. I don't know if or when I should test or if its my hormones balancing out. Has anyone had anything similar ? Currently TTC thanks xx
