When would you guys test?

My daughter was born July 8th. I had PP bleeding for 4 weeks and it completely stopped until I got my period at 6 weeks PP. I was a normal 5 days I also started the mini pill again (I should mention I got pregnant with my daughter on this pill) I went back on it because it was the best option for me and on top of the pill this time we use spermicide every time as well. I did have sex starting at 5 weeks pp. Anyway;

I haven’t had my period since August im wondering when I should worry about pregnancy being a possibility if at all? I know the pill can completely get rid of your cycle so I’m unsure. I have no symptoms but honestly I had no symptoms with any of my pregnancies
