Hey all I need some advice

I’m on medication to start my 4th FET

But I feel like this cycle is taking longer then all my other cycle

I went yesterday for a scan thinking I was going to be given a date for next week to go ahead with transfer but the doctor scanned me and said your lining is good at 8mm but we won’t be doing transfer next week only a scan to see how your lining is. I’m abit worried as that will mean that it’s going to be another 2 weeks and glow has said I’ve already ovulated yesterday. I said to the doctor what if I come on my period and he said you won’t the medication stops that. Is this normal as I’m really scared that I will be getting my transfer too late
