Weird question. Has anyone on here heard thatif your child is teething early (which my daughter is 3 months and dr confirmed she is) that  that means you are going to have another baby soon? This is what my fiances mother said to me. I had sex a week before my pp visit and its been almost two months since then and im on the implant birth control and before i got it i took two pregnancy tests that both said negative. So im good. But she has a daughter thats currently pregnant who is 7 months and another daughter. I do not inderstand why she is bothering me to have another child 3 months after her son and i just had our first!!!!
