Fibroid tumor?

My lower back hurts
My boobs stopped aching after a month (right after my 3-day period) - I HAD BROWN BLOOD on the 3rds day.is that normal?
When I had it my cramps were different I feel like my stomach is bigger.
My right leg hurts or cramps a little
I gained weight or my tummy is bigger and hard when touched.
I had 2 other periods before the last one but they were light too.

I didn't have sex, I just dry humped fully clothed. 1 time I was only in pjs but he had pants and boxers on.
blood test came hCg less than 2 after 13-15 days after possible conception. all the hpt preg tests came out negative.it's been 7 - 9 weeks. What could this be?

I feel flutterings in my stomach. I had a bad cramp on my left leg, is that normal? how was it tuspposed to feel when u r p? should I take the test?
IF it might be fibroid tumor, i would bleed a lot, but I don't. Is there any case where it could be... I really don't know.

this question can better be answered by your Dr who knows you away better than we do=good luck on your check-up
