Do I need to restart 30 days no contact?

I haven’t seen my ex for 4 weeks, I went no contact straight away but she’s initiated contact a few times and I’ve mostly replied (though not eagerly, I made it clear I would talk only if she wanted a reconciliation and I respect her decision). The longest is 7 days without contact, after which she text me about a funny memory and I didn’t reply. A day or two later, I then saw she posted a picture online with her ex and I then contacted her and the conversation was heated/angry. There were also texts saying how could I suggest she was back with her ex, she was in love with me still and thinks about me all the time. The next day I phoned her and apologised and we had a lighthearted conversation, she said she missed me and didn’t want me to hang up. Do I now need to re-start the 30 days no contact? Should I have ignored her all this time? She originally said I was the right person, just the wrong time.
