Any suggestions!!?? Please help :/

I recently turned 38yo, had m/c in July, tracked my bbt, o-day, etc.. since my m/c till this month to get a break from the stress, now no period has shown the past 45 days (my cycles are regular 26-28 days long), have had 2 negative hpt's. Yes I do have PREG symptoms like nipples tender, frequent urination, fatigued, nausea, moody... but ever since I've been really trying each month, I feel the same, at this point those could all be psychological. Any other ideas of what it could be? I'm worried & scared, praying it's not early menopause!! 🙈 (sorry this is so long)
