Whats should I do?

’ve been on the pill for over 6 years and have been with my now fiancé also for 6 years. This past year I started getting more comfortable with not using a condom. I always make him pull out, but these past couple of months I started letting him finish in me, but I only let him do that when I’m close to starting my cycle. (He came in me Wednesday).

I know that your period changes once in a while even on the pill, and I’ve had many periods where my cycle is short and very light, but because I haven’t been extremely safe like I used to be, I’m worried this is something different. I usually start my period on Sundays, but for this cycle I finally started Monday night. I had little bit of brown discharge this morning, but now it just stopped. I only had a little bit of brown, and now the rest is normal discharge. I took two pregnancy tests, one yesterday and one today and both are negative.

Should I go to the clinic and ask for blood work to be done or should I wait to take another pregnancy test? I’m picking up my new pack of pills later, so I’m stressed about what I should do right now.
