Gyno Question at the End of Cycle

I’m currently at the end of a 10week 400mg/wk super test 400 (150 E 150 Cyp 100 Prop). I did my last injection on Saturday and now I’ve started to notice a little bit of gyno symptoms. There is a feel of tissue underneath my left pec and in general it looks a little different. This just popped up two days ago and I Was curious if I should start taking the nolvadex immediately at a dose of like 60mg/day or wait until the test has fully cleared. If I do start the nolvadex right away to stop the symptoms to I just continue to take it through PCT and make my PCT an extra week long or so? Any advice would be greatly appreciated.

My planned PCT was:
week 10-12=nothing
week 12-14- 40mg nolvadex ed
week 14-16 20mg nolvadex ed
