September- AF came on the 3rd. october- AF came on the 9th. November- AF still has not come(today is the 17th). before this my period has been relatively regular, coming maybe a day later every other month. I have had some pinching pains in my lower stomach and the other night in my vagina as well. I have taken hpts that are negative. could i be pregnant? what could this be? should I see a doctor? 🤔
