Hello, I had a birth control implant in my arm around 6 rmonths ago and I had some bleeding at the start although I haven't had my period at all.

I've been having unprotected sex and I'm wondering if I could be pregnant or if there's a reason for this?

I read that I might be pregnant if I hadn't had my period in three months.

I understand that I should go to the doctors but I cannot right now so I came here to get some help, thank you.
