Maybe baby!

My period is supposed to start on March 2nd. Anyways my husband and I use the pull out method, I know it's not a reliable form of bc but we have bad luck with condoms. So for a couple of weeks my dd who is 18 months old has been extremely clingy like she can only be in my arms and no where else which is extremely rare because she is an independent child. If I ask her to get her baby she will rub my stomach and my husband keeps on telling me I'm pregnant. My blobs he says are bigger I've been super emotional for no reason my nails are growing pretty fast and the pants I wore several days ago are so small I can't button them. I'm afraid to take a test because I don't want to know the answer. Thanks
