In the Name of Allah, the All-Merciful, the Mercy-Giving.

 

In case of real divorce taking wife back can be in a formal way or informal way. It could be in an actual statement or a kiss or a hug or an intimate relationship like you described. So if such things happened during the 3 months period after the word of divorce happened it should be fine.

 

But in your case as you mentioned he said it while you were on your period and for that it does not count at all. You are still his wife and everything is fine no need to worry insha Allah but he should be advised not to come back abusing words of divorce threatening the stability of marriage.

 

Almighty Allah knows best.
