Weird AF?

Hi ladies. I usually have a very normal period, 5-7 days heavy in the beginning, and then gradually reduces as the week progresses. Well my AF was due 12/2 and it showed up late on 12/4...but barely. I spotted extremely lightly 12/4 & 12/5. On 12/6 it was very heavy, and 12/7 it was heavy in the morning and then gone at night. Now this morning 12/8 it's not even heavy enough for me to wear a tampon. So basically I had a 36 hour period? Has this ever happened to anyone? I've never had such a weird period. My husband and I have been trying to conceive and I've been tracking everything issuing glow since June so I know this period is abnormal. Any thoughts or advice from anyone would be appreciated!!!
