Help needed!?

Ever since I had faint lines on 4 pregnancy test back in April I've been experiencing pelvic pressure!! Mainly when I sit and lay down and even sometimes when I'm standing!! It's a heavy sensation in my uterus area. I didn't have a cycle in May but I had 2 light cycles in June. They both arrived a week early and this last one I had NO cramping whatsoever which is unlike me I have no idea what is up!! Help anyone?
