5th month TTC, got period today

I’m 32 and have regular periods (27 days every month). I’ve been using OPKs and making sure to have sex every other day during fertile window (5-7x around that time and use pre-seed). I thought this month would be our month. No period until day 30 this month; then has just slight light pink spotting.

I’ve never let myself get too hopeful this month just in case but I did start to feel really excited yesterday when it seemed like all my symptoms were different than PMS. I even got nauseous with different smells and wasn’t hungry.

Woke up this morning to full on period. It’s so easy for me to think about this logically for the rest of the month, but why is getting your period again such a crushing feeling? I told my husband and he looked so sad. We really want this baby and can’t figure out what else to do differently. I know the answer is to keep trying but all I want to do right now is cry.

Any advice? Any good ways to cope?
