Hormonal imbalance?

 Currently trying for #2. Took 8 months to conceive #1. Narrowing in on that timeframe again. Getting positive ovulation tests every month, trying in every window...even before and after for good measure. Each month I'm certain that 'this is gonna be the month.' But then I get sore breasts and start spotting 7+ days before AF is due. With my first pregnancy I didn't have any premenstrual type symptoms prior to BFP. I'm 36 and starting to think there might be some hormonal imbalances. (Read that spotting early might mean too much estrogen. Anyone else know that to be true?) Heading to Dr early March to inquire. I'm starting to think #2 might not be in the cards ... Tired to trying and riding this emotional roller coaster.
