Fertility worries

Sarah 💗
Im normally really regular, with 28 day cycles. I'm 25 and have two children already. I had abnormal cell treatment about 7 months ago and we have been trying for 6 months. I know that isn't long but my other two were conceived after 1 month. I am so hormonal all the time, moody, sore boobs, huge appetite and my periods are all over the place! I'm 7 days late and they're getting more and more irregular. I'm worried that something may be wrong with my babies bits?! 😔
