No period fustration!

Hello all,

I will appologize now for lack of abbreviations, for i am new. I am very fustrated, my husband and myself were going to start TTC in May, but he came down with Shingles, and then i came down with Chicken Pox. Now we have to wait three months before we can even start trying :(. So the fustration comes from my irregularity. My last period was March 24th, yes if you do the math its 70 days ago. I have never been regular, but this is a little annoying since we are going to try in two months. I have my doubts that i will even get my period by August when we want to start trying. My doctor does not seem concerned and says that i am perfectly healthy. i will back up a little and fill you in. I was on seasonique(3 month pack) i loved it! I came off of it in March and got my period, but it was VERY light and only last 2 days from start to finish, no spotting nothing. That was the last i have seen of anything. Normally it last 3-4 days with some spotting for up to a week. I chalked it up to working out. In January i got back into the gym from a year break and started working out and doing the eleptical for about an hour and would do anywhere from 6-7 miles. I am not overweight, nor am i underweight i am 144 5'6" size 8 with a bmi of healthy. My whole life i have been active. Is anyone else going through this? Does anyone have any recommendations? Oh and i am not pregnant, took one of those last week.
