I had sex a few weeks ago. Been constipated for weeks even before I had sex. I bled 1-2 days after sex and it was enough to fill pads and lasted a few days. I’ve had pains like sharp pains in my back and stomach area. My stomachs sooo hard can it be constipation? And today I ovulated and I had blood in it but last month I had the same thing is it normal or should I be concerned I might be pregnant?
