Help?

Hi ladies. Im clearly lost at this point. But ive learned to listen to my body and as of yet ive been right to trust my instincts. Last full cycle was dec. january was spotting seen only when i wiped that lasted 3 days. Nothing in feb. Either im pregnant and havent seen a positive result yet or i feel somethings wrong. Im adding a picture to show this "bulge" i guess you could say i noticed this morning. Its firm to the touch. Im wondering should i ask for extensive testing to determine whats hoing on. Advice? ​
