Period came 8 days early?

[Lozz4]

hi so I'm new to the whole 'conceiving' thing and new to the site . I've been reading all the posts and need some advice . me and my fiancé have been trying since November last year but I was diagnosed with an ovarian cyst in December which is still there now. my day of my last period was 4th April and my ovulation was 15th which has changed because my period has started 8 days early , so ovulation would of been the 7th. I started spotting last night and this morning there was light to dark red blood and I'm using a tampon and pad. I've got really bad cramps , nausea , tired and headaches. me and my partner had intercourse 6th , 8th , 10th and 17th . sorry to babble on just really need some advice as I'm confused because my doctors want to put me on the pill as we've sort of given up trying :/ . just really want to be pregnant .
