Have you had your thyroid checked? That can cause very long cycles (and often weight gain and holding onto weight as well). I had a thyroid issue where it was slow, called hypothyroid, and had periods every 3 to 4 months (with pms starting at 3 weeks in and lasting until my period came, pms can be a little like pregnancy symptoms so it was confusing AND annoying). Changes in routine and increasing exercise are notorious for delaying periods too. You sound like you are doing the right things and remember, it takes the average couple a year to conceive. Have you talked to your doctor and told them you are TTC?
Yes I have told my Dr that I'm trying to conceive. My Dr tested me for my thyroids and it is normal.
I haven't took a pregnancy test yet and I will let you know.
I took a pregnancy test this morning it was negative and my period came on this evening
