Possibly pregnant?

Rae

I did the do on January 14th. I am on birth control however in January I wasn’t very good at taking it. I missed about 4 pills that month (about one a week).

I was seen at the gynecologist for an annual routine on the 20th. I made a comment about my breasts being tender and she said my period should be starting soon. It’s now the 1st of February and there’s been no period, my boobs are still tender, and I’m very nauseous. I took a pregnancy test on the 29th— 15 days after doing the do— it was negative but I could’ve sworn I started to get a bit of line eyes around the 8 minute mark (10 minutes was the toss it mark). But now I’m very nauseous with still tender boobs. WHAT DO??

** I have a 9 month old so I’ve been pregnant before. I felt nauseous during the entirety of my first trimester.
