Could I be pregnant??

To start off, in Febusry my period was a whole week late, I took the pregnancy test and they were all negative. AF showed up feb 29th. After that my husband and I have actually been TTC. We had sex at least 4 times a week and def during my fertile window multiple times a day. *In my mind there is no way someone could not be pregnant because he came inside of me so much this month (March) but anyways my next period wasn't due until March 30-31st it came on March 28th which is weird because my periods are always on time. For the last year or soi have been having 31 day cycles. I did not cramp or anything leading up to this recent period. I think I cramped the day it started but they were not as painful as normal period cramps. It lasted 2 days, moderately heavy, the a day of spotting (the spotting was only when I wiped, nothing on the panty liner) it has been 4 days since the bleeding stopped and I am very bloated and get cramps every now and then. I get this feeling like I'm about to get sick ( nausea) and my husband thinks I'm getting bigger (hopefully I'm not gaining that much weight lol) I have taken pregnancy test but they are negative. I really feel pregnant. What do you guys think? Could I be pregnant?
