I missed bc pills now have pregnancy symptoms. Can you help me?

[MommaAsh]

I'm on portia birth control. But the last couple months the pharmacy has switched my birth control between portia and another one I was on previously. On may 3 through may 9 was my placebo pill week. I had my "period" may 6-9 and had no more bleeding on the 10. May 10 was the first day of my active pills for the month. On may 15 and 16, I missed my pills. I took 2 pills on may 17 but on may 18 I dropped one and couldn't find it so I only took one. On may 18 I started having breakthrough bleeding that didn't stop til may 22. On may 20 I had unprotected sex with hubby (no back up birth control). On the 26 (6 days after sex) I had more bleeding but this time it was only when I wiped and it only lasted an hour or two. Since missing those two pills, I have backaches, light cramps, quick sharp/tugging pains in my lower stomach, tender breasts that feel like pins and needles or burning sensation (idk how to describe it). It's been 8 days almost 9 since having sex with my hubby and 13-14 days since missing my first pill. I just would like to know what your thoughts are as far as if I'm pregnant or just having symptoms still of missing those pills?
