Worried... No period after patch

I was on the patch for a month and a half. I forgot to change the patch and when I remembered it was 5 days late. So I ended up taking it off completely the day after I would have put the 3rd one on (one week before the off week) I got my period the next day which made my cycle an 18 day cycle. First cycle on the patch was 28 days and my normal cycle before the patch is 30-31 days. I'm now on CD 33 and no sign of AF. Does anyone have experience with the Patch? We're going to start trying again in August but I'm worried I'm infertile now ;((  all hpt's are negative.
