Confused. Need advice

Hi, I'm TTC for last five months. Now the thing is I am having late period for last two months. My normal period cycle is 25-27. But last month it was 32 and this month I still don't have period..so confused and this is my first time!!! My pragnency taste was negative. I did it yesterday. I feel like something is coming out from there but when I check it, its nothing. (You know what i mean)....so I don't know what to do! Please tell me if anyone has gone through this. I just need to know if it is normal to have sudden late period 😕
