guys help me I'm overthinking I think

So I had my guy give me oral and fingered me on Friday night but wasn't sure if his hands had any precum as he told me his hands where dry plus his penis didn't seem wet but it was dark too can't trust my hands only! I'm on the alesse pill do you guys think it's possible to get preggo? Today also took it an hour late and I see very slight spotting almost to none is that from the pill? Please help me
