Miscarriage ?

After getting positive pregnancy tests, I woke up last night with terrible cramps and spotting.

As the day went on I was still bleeding and the cramps are getting worse.

Do you think I’m having a miscarriage or could I still be pregnant?

Me and my husband have been trying to conceive for over a year and when I finally it that positive pregnancy test I was over the moon.

Also I’m on anti depressants? Could that cause a miscarriage?
