I have been tracking my ovulation and I know I ovulated 7/21..bbt rise, positive opk, ewcm, ovulation cramps...now I am 26 dpo and getting negative hpt..has anyone had a cyst that caused them no to have a period or a period very very late....I just had surgery in may to remove a large cyst so I doubt I have another one said my dr but my period is really late..2 weeks late...now with the negative pregnancy tests I think its a cyst.....has ANYONE had a cyst that caused them such a late period????
