TTC and just feel like giving up!

Ariana
My husband and I have been trying to get pregnant for what seems like ages now (almost a year). I have a baby from a previous relationship, he's 3 now but I got pregnant with him while I was on the pill & now I can't seem to get pregnant again! I'm so overly frustrated, & I try not to stress and just tell myself that it'll happen in time but it makes me SO angry when my AF shows it's ugly mug. I'm supposed to start tomorrow, so I'm prayinggggg it doesn't come. Sorry I'm ranting ladies, just don't know what more I could do!
