Rising BBT, 38CD, & BFN

Ashling

So Ive been tracking my bbt and for the last 5 days it has kept elevated and rising, I believe I ovulated last week(never got a peak on an opk - got very close - but had many days of EWCM w/ and increase then drop in bbt). I took a pregnancy test today but it said neg. I'm between 3-5 days early before projected period(I am very irregular - sometimes I only get one period a year). Did I test to early? I know I should see a doctor for the irregular periods, but I am afraid that they'll tell me that I can't have children. I never wanted kids until I married my husband a few years ago, and felt safe and secure enough that having children would be okay. I don't want to know that now that I want kids, that I should have been keeping the thought of not wanting them cause it wouldn't hurt as much. Anyone dealing with very irregular periods and never knowing when you ovulate or when to take the damn test??
