Has anyone ever gotten their rainbow baby right after they had a chemical? I just had a chemical on the 12th of September, I tested this morning & got a positive on my opk! I thought it would’ve taken longe but I guess not🤷🏽‍♀️ can someone give me a little hope!?? Please share your stories with me 🥺 it would really make this a lot more easier & hopeful for me 💛
