Kinda freaked out, what the heck is up with this?

I am having a feminine issue and I am a little freaked out. My period started on the 8th of this month and lasted about a week. I had dark brown discharge for about three days after the active bleeding stopped. Then I had about three days with no discharge. About two days ago I started cramping again and started getting dark brown discharge again. Today I had a gush of bright red blood (about two tablespoons worth). I called my OBGYN since I had already had my period this month and it just ended about a week ago. She said to call if it happens again next month and make an appointment to come in. I haven't had two periods in one month since I was about 14 so it has been over 10 years. I sighed and put a tampon in to settle into another period. I took it out to take a shower and there was only a little red blood but a bit more of the dark brown discharge. What is going on?

Facts about my sexual health
I had a pap smear 3 months ago
I have been taking Errin BC for just over a month
I took a pregnancy test on the 5th since I didn't have a period in December but it was negative
my husband and I had our first condom free sex on monday the 21st since I had been taking Errin for a month
I have never bled from sex before and it was two days ago that we had it

Please help! What was up with that sudden gush of bright red blood? I have never spotted before and I don't know if that's what this is because it was only a few teaspoons and now it is back to dark brown and it seems to be tapering off even though I am still cramping.

Thank you!

Sounds like it might be some breakthrough bleeding, or your cervix was irritated.

Probably your bi rth control.

What is breakthrough bleeding?

It's bleeding that "breaks through" when it's not time for your period. A lot of women have it when they start BC the first time, or when the switch BC. It's your body adjusting to the hormones.

I agree that it's probably breakthrough bleeding. When I started the pill my second month on it I started my period again a week after it had stopped, even though I was taking the active pills.

Thank you! I had never heard of that before!
