Re

So I got my nexplanon out yesterday and my family knows now since they saw the wrap around my arm. Anyways, my daughter is 10 months and me and my fiance wanted to try for another one after her bday or in april (my family doesn't know)

And my family wants us to wait like 3-5 years to have another baby... i know im going to get pregant soon. I just dont want to disappoint them... and i dont want them to be mad at me.. i dont know what to do or what to think because their opinions mean a lot to me since their my family 💔😔
