Helllpppp 😳

so according to last months predictions I had unprotected sex a couple of days before I ovulated (I don’t take the pill or any contraception due to health), my boyfriend is always super careful, but I am 13 days late on my period, waiting for the second one since I had my IUD taken out... however over the last week or so, I am so tired all the time and have had the slightest spotting... my boobs are also super tender and I get irritated quite easy and also need to pee more frequently.

What are your thoughts?

Before you state the obvious ā€œyou had sex without contraceptionā€ blah blah I’m looking for some honest advice please ladies!
