On birth control and might be pregnant!

Tr

I need help. I am NOT CRAZY! So I am on a birth control. I don’t get periods or ovulate. Because of health issues when I do so. So About 2 months ago I got put on an anti seizure medication to help a little bit of bipolar issues. Well I’ve been having some signs when I have been pregnant before, so my husband insisted I test. I tried for a long time to get my first baby so I know I have the line eyes lol. And about at 2 minutes I could see the faintest line. Hubby could see it too in certain lighting and angle. I feel stupid even adding the picture because you can’t see anything but I swear it’s there. My question is. I have no idea when this would have happened how do you know how far along!? And I will probably go get a blood test Monday but I took the test a few hours ago so not fmu. Should I take a test in the morning and see?
