Any insight on irregular periods?

Kat
Hubby and I have been ttc now for 7 months. Its been difficult because my cycles are irregular but I know for the past 3 months weve been dtd before and on the day I ovulate. Last month I had a day of light brown spotting and then af showed a week later. 5 days early. This month I was positive I was pregnant bc I was 4 days late and my average cycle is 27 days; had eggwhite stringy discharge which I never have before a period coming and a lot of creamy cm. My last period was march 5th and now af started today😢. Does anyone else have irregular periods like this ans was able to conceive in less than a year?
