Could I get pregnant this cycle ?

Ka

I’ve been wanting to surprise my fiancée for Christmas by telling him I’m pregnant. He has no kids and he’s a bit older than me by 14 years. We both expressed how we both wanted children and we’re both ready. The only problem is we’ve been trying for six months and still nothing. We used PRESEED this cycle so I’m hoping we’re pregnant. Any advice to what could be delaying me from getting pregnant?
