Pregnant Again?

So I was supposed to start my period between this past Sunday-Saturday. It is now Monday and nothing. I wasn’t honestly going to start worrying until mid week. Yesterday my daughter started going for my breasts. That was odd since I only breastfed for 3months. I am on birth control and take it on time every morning. However, I just realized that I was on antibiotics earlier in the month for a sinus infection.

Fast forward to today—My boobs have started to have a sensation. I gently pressed on my boobs and a some breast milk came out. I obviously will take a pregnancy test after work. However, I wanted to see if anyone October Mom’s have had a similar experience and what was the outcome.
