[Maybe TMI, Long Post] Late by 9 days, cramps, discharge, 2 (-) tests! SOS!

Hi, Everyone!

I'm hoping to get some insight and/or advice. I'm very nervous & emotionally distraught 😭

So, a little background-- my period has been on time for the most part for about the last year or so. My cycle has always been pretty strange, but it seems as though once my SIL got on birth control about a year & a half ago, my body has adjusted and synced with her. On average, I start my period 2-4 days after she does; & it's extremely rare, but sometimes I start mine 1 day before she does. She started her new package of BC on March 25th and she started her period on March 19th, so by that logic, I should have started mine on the 21st to the 23rd. eve says I was due on the 25th.

My last period was February 24th - February 28th. According to eve, I am now 9 days late. 6 days ago, these horrible cramps started, I was stuck laying in bed in fetal position. That lasted for 4 days. The severity would come and go. I'm lacking an appetite. I'm extremely fatigued. I'm moody, at times feeling pretty depressed. I've been nauseous on and off-- certain smells are making it worse. My husband is convinced I'm pregnant.

With my son (born May 2017), it took 4 pregnancy tests before it came back positive. I was 20 days late when it finally tested positive. Before then, every one was negative. So far, I've tested twice and they're both negative.

So my question is, what are the chances that I'm pregnant or do you think it's possible it's just a random missed period (I have had that happen, but not in over 3 years).

Thanks, everyone!
