Hi ladies! I'm currently in my TWW and I have noticed some mild cramping that started late last night and again this morning. It's nothing painful just enough to let me know they are there. I'm not sure what day I ovulated on, but I suspect I'm 4 to 7 DPO according to my signs and symptoms. I have also noticed an increase in pelvic fullness/bloating since ovulation. I also been experiencing a funny feeling in my chest and dizziness, which is kinda scary, but could just be my anxiety but i feel calm and happy :) Has anyone experienced this before? and what could be the cause or causes? TIA! I'm off to do some researching!
