Confused!!

Sarah

My cycle is all crazy...I had a very long 53 day cycle in January (it was because I was so stressed). February my period was from the 3rd - the 8th.  Well now I have no clue when to expect my period. One app says the 9th, one says the 15th, one says the 19th and the last one says the 28th. So I have no clue when to test if I have ovulated. My cervix is so high I can't reach it and it feels very closed. My CM is sticky/creamy now. So I'm stuck. When would be the best time to test since I don't know when to expect my period???? All the tests I've taken have been very faint. I'm confused. Anybody got any advice for me???
