Weird period all of a sudden? Very heavy

Aubrey

So I’m usually very regular with my period every 28 days and I take my birth control every night. My period isn’t very heavy at all usually. It’s been about two weeks since mf last period then all of a sudden yesterday I felt like i wet myself then I look and I bled through my underwear st work... as of today I’ve bled through about 6 underwear’s but I have little to no cramps.... and when I do they’re on the right front side only. I’ve been feeling very weak as I’m anemic and this is a heavier period than usual but I have novclotting and it’s my second one this month. I also feel like my vision is going weird and my boobs are VERY tender. Has anyone experienced before or something similar?? My birth control is monolyssa and my gyn appt isn’t until Thursday :(
