Discouraged and lost


My fiance and i have been TTC for over a year. Everything was fine at first until i started bleeding every 8-12 days for about 3-4 days at a time. I went to my gyno and she told me to track my period and see what the pattern is. Of course, after trying so long i started getting discouraged. Seeing everybody around me get pregnant and bringing up another child around me asking when i will have another, got to me also. The last time I went to my dr she told me she wanted to put me on BC for 3 months to see if it would help regulate my bleeding and maybe help with ovulation. I just finished my 2nd month of birth control and my heart just keeps telling me to stop taking it. Its just hard bc i was 17 when I had my son and it wasnt planned, it just happened, but now that my fiance and I want to try its not happening. My fiance isnt my child biological father so i feel like my body is failing to give him something him and i both want.

It also doesnt help that my 4 year old came up to me and said "mama youre getting a baby in your belly". What would you do if you were me? Im so conflicted between stopping my birth control or taking it another month and pushing the possibility of pregnancy back some more.
