However, I have had a ton of spotting this month which is very unusual for me. Because of the spotting I didn’t want to have sex with my boyfriend because I was afraid my pill was failing. But on the 11th I was messing around with my boyfriend and I sat on top of him. We didn’t have sex because if I was going to ovulate, that’s the day of the month it would have happened. His penis never actually entered my vagina, but it was around the area and I’m not sure if there was precum. Anyways, I went to the doctor and they didn’t seem concerned at all. My doctor did switch my birth control to a higher dosage and she told me I could go ahead and start taking it right away but my period is supposed to start in three days. Should I go ahead and start my new pill today or should I wait and see if my period starts Friday. I had some pretty heavy spotting last week for two days that seemed like my period so my doctor is unsure if I will get my period on my placebo week since everything went funky.
