Confused

So my cycles are random and hard to track. My fiancé and I tried using preseed to help our chances at getting pregnant this month. It’s been about 4 weeks since my last cycle and no period. No symptoms other than insomnia/tired all the time and just in the last 3 days my clitorus has become swollen and uncomfortable... it bleeds too which I read online can be early signs of pregnancy since increased bloodflow will cause swelling and bleeding down there. I’m afraid it may be too early to test for me because of how small over the place my cycles are... should I test or wait another week then test? I really don’t want to get my hopes up ...
