i use to be on the nuvaring but I recently decided to go back on the pill, I started my new pack and I was on the first week and me and my boyfriend had sex and he finished inside and we didn’t use protection. I’m suppose to be getting my period next week but a couple days ago I noticed that I have some dry blood when I wipe and this has never happened to be before. Since I had not finished my first full week on the pill when we had sex could I been pregnant ?
