I need help ! 🥺🥺

Hi guys, I just want to share my pain with you, so last month I got my period delayed for like a week, we didn’t really try for a baby so mostly we used pull out method and like 3 times we had it in. And I thought so since my period delayed I was pregnant. I mostly have longer cycle but since December to March I just had 30 days cycle. Las month it got messed up and was longer to 40 , so I did a pregnancy test and it came out negative. Then after some days I had a appointment with my doctor and he made me do some tests and a scan and everything was normal. And after some days I had my AF. And this month we had a lot of BD since this month we started trying for a baby. And now again this month my cycle have been to 40. I didn’t track my ovulation. But since I get longer cycle I’m afraid to take a test. And I have been wondering what could be the cause to a. Longer cycle . I’m sharing you my scan report. Guys please help me out
