Idk what’s happening

So I woke up to a really heavy period like going threw a pad every hour that all started at 4:30 am. I’ve always had heavy periods but this one was a lot worse. Well about 3 pm it stopped and I wasn’t bleeding then at 4 I started spotting and I don’t know why. I don’t have pcos or anything wrong I just had a check up last month. My husband and I have been trying to get pregnant for a year and nine months. The doctor said he won’t start me on fertility treatment till I lose some body fat I lost 10 pounds but all of a sudden I can’t lose weight I’m eating healthy and workout twice a day 4 times a week. Idk what to think.
