Since 1dpo I have been having a dull cramp throughout the day. I normally get ovulation cramps before I get my peak. But this time I had my peak 6days ago and had nothing before hand. I've also been having quite a lot of cm which is creamy.  I know I ovulated on cycle day 17 (17th May) because I also temp. My period is due 1st June. Can anyone shed any light on why I am constantly having a dull achey cramp. Also I've had insomnia, sore nipples (shooting pains), backache, indigestion, cold type illness, major nausea.
