7 months post birth control...

Okay, so I was on a pretty basic birth control for about 3 years when I decided to stop taking it due to some extremely uncomfortable migraines that started shortly after starting the pill.

This was 7 months ago. During this time, my fiancé and I decided we wanted to try to conceive about6 months ago.

Now I don't remember what my period felt like almost 4 years ago. I only started the pill to avoid a pregnancy and no other reason.

Since stopping the pill, the only symptom I've really had was moderate cramps.

Last month I had a chemical pregnancy.

Now this month, my symptoms are absolutely crazy. Extremely sore boobs, severe cramps, nausea, and migraines.

Normally yes, I'd be excited for these because it all sounds like a pregnancy to me, except my period came and I feel absolutely awful.

Is it normal to have such strong symptoms after a chemical pregnancy? Or even for them to start 7 months after discontinuing the pill?
