With drawl no period

Natasha
Hi. I had a withdrawal bleed about 3 weeks ago now but still no period. My boyfriend and I have been using pull out method. I took a test and it was negative around 4 days ago. Is it normal for my periods to be messed up when coming off it? I've been so depressed/low and no sign of pregnancy at all. I just recently got diagnosed with PMDD. Thanks!
