Pre-eclampsia & Age gap

After having a hard pregnancy with pre-eclampsia & our beautiful daughter had a cows milk alergy, for first time parents we found this hard I’m not going to lie. We have now decided to try for a baby, I’m a little scared of having pre-eclampsia, has anybody had this second time round?

Also do you have a big age gap with your children? Mine is currently 6.

I’m new to this app & just starting to track my periods. Has anybody found this app to be accurate?

Any advice would be much appreciated 😊
