From a lady who has had a miscarriage too, the anxiety never completely goes away...so what I suggest is setting small goals (especially once you become pregnant again). This means taking each month at a time until you get pregnant again...(once you are pregnant, set manageable goals...mine were get to 6 weeks -had ultrasound, 9 weeks-when I lost the last baby, 13 weeks- 1st trimester over, 20 weeks, 27 weeks, 36 weeks, and last 40 weeks! It seemed to help to make small goals!)
Feeling ready is the first step (I too was ready right away...and know that negative tests/period coming will hurt...thankfully, I only had one full cycle after mine before I got pregnant again, but I cried and cried when I took the negative test after being a day late and then cried more when I started bleeding.). Sadly, people may make comments about trying again right away...just try to ignore them! My response was always "I will always love the baby I lost, but I am ready to try again!" and most people didn't have much to say after that!
For telling people, I thought I was going to want to wait until 12 weeks, but once I got pregnant again, I was SO excited that we ended up telling family at 5 weeks and everyone else at 7 weeks!!! Go off what you feel comfortable with!
As for everything else, what every you feel is completely normal...you may go one month and feel fine and then the next you cry and cry! It's all normal! Good luck and hope it happens quickly for you! If you have any other questions, let me know!
