So we're TTC for four cycles now. Today the spotting started so my period is on it's way.. I know that it isn't that long but it's the first time I'm really disappointed.

I've used this app (and another one) from the start, did ovulation tests, we had sex every day of my fertile period,..

I can't shake the feeling that there is something wrong. Since we started talking about TTC I felt like 'it's not going to be easy'.. Do you guys have any tips for me?
