Trouble conceiving

Jennifer

I’ve been with my love for almost 2 years and we recently got married.. im 35 and he’s 23...I have a 13 Year Old and 7 year old from previous relationship ... he doesn’t have any children but we would love to have a baby together. We have been trying for over a year.. I thought this month was it since my periods are almost predictable but in November I had my period just like normal then 10 days later a started lightly bleeding off and on for 4 days which isn’t normal.. (I thought it was implantation bleeding) but after multiple otc negative test results.. I’m crushed and heartbroken!!!
