My periods late, but 2 negative pregnancy tests.

[Robs1897]

My period is 18 days late. I've taken 2 pregnancy tests in 2 weeks and they've both been negative. My husband & I are TTC. My period has been late before but never this late and I've never missed one while I've been off birth control. I've been off birth control for 3 months. I've read that missing a period can be a sign of thyroid problems. Should I go to the Dr?

Hi.  The negative pregnancy tests are probably a good indication that you aren't pregnant this time.  I'm sorry.  But until your period comes, there is always hope.  You could have ovulated later than you thought and then you'd not get a positive as early.  I liked the early response tests when I was trying because they are super sensitive and you can get a positive up to 4 days before your period is due.  So, periods can be late for a variety of reasons and out of nowhere with someone that is usually regular.  Illness, changes in routine, weight gain or loss, stress, etc. can all affect cycles and make them longer.  And yes, a thyroid issue can as well.  I had a slow thyroid for about a year and a half called 'hypothyroidism' and I got periods every 3 to 4 months.  It righted itself, thank goodness, before I even started thyroid treatment.    Other symptoms are dry skin, dry hair, gaining weight (I know, it's lovely sounding, isn't it?).  But you aren't there yet to jump to this conclusion.  I had my levels checked and it was determined.  I'd give yourself more time to start your period---  if you go up to three months, call your doctor and be seen.  That's how long I went and at that point I started working with my doctor. It's really hard when you are TTC but hopefully it will all work out soon for you hon.  good luck
