I need some of your wonderful knowledge!

Hello beautiful ladies , I have a question I was hoping someone could answer for me . My man and I have been trying to conceive for about a year now with no luck. But I did have a strange experience a couple of months ago.

My period was late so I took a test, it was negative so I figure my AF was just going to be off that month. I waited and waited and nothing ! I kept taking test every couple of weeks and they all kept coming back negative . It went on for two months so I hadn’t had a period in three months . All the test were coming back negative , so I scheduled an appointment with my Doctor and took a test that came out negative so she ordered an ultrasound. (This part is TMI) The day after I was at a family event and felt a gush of liquid come out of me . I ran outside and my pants were soaked all the way to my knees . I went home and checked and there was no blood. I called a friend and her mom who was a nurse told me to check if it smelt sweet to see if it may have been a miscarriage, it didn’t and no blood followed it . I started my period a few days later and I canceled the ultrasound.

We have still had no luck conceiving and now looking back I wonder what that could have been. If anyone has experienced this or knows what it may have been please please let me know ! Thank you!
