Bad news...

We’ve been TTC for a little over a year now. I’m 24 and my husband is 25. We have a healthy 5 year old and we’re ready for another. I was 3 days late on my period (never been late before) so I got a little excited...until I started today 😩. Every time I have a period my husband gets super upset that we aren’t pregnant yet. I’m not sure what’s wrong with us...but we are taking vitamins and prenatals, not drinking, doing ovulation tracking etc. 😞😞 any advice?
