Confusing TWW

I came off the pill early August '17 and since then my cycles have been about 35 days. Was due for AF on Dec 27th. I did a FRER hpt on Dec 25th which came back positive, got bloods drawn on 27th, came back at 15 HcG and then at about midnight on the 28th I started bleeding. Bloods taken on 30th were less than 2. So I had a chemical pregnancy last month. Now I'm not certain exactly when I ovulated this month (assuming I did at all). Glow initially predicted my most fertile day to be the 19th but when I logged on that day it had reverted my most fertile day to the 17th. Luckily for me I had BD on 13th, 15th and 17th.

So now I just have to wait and see what happens next.... I'm assuming AF would be due 1st or 2nd Feb. And I feel so anxious not knowing if I made the most of my chances this month! But I'm very reluctant to do another early test this month due to the frustration/sadness that came with the chemical pregnancy.
