I’ve been on the pill for 8 years and finished the first week of December. Had my withdrawal bleed and have only DTD twice since then (been ill). I have been feeling nauseous with odd sensations in my stomach then this morning have had a sudden bleed (Brown in colour and thick) that is now almost stopped. Could this be implantation bleeding? Could I be pregnant? Totally new to all this so apologies if I’m missing something obvious.
