Ttc, 111 days late for period. Irregular cycles previously. Opinions?

Aimee
I'm currently 111 days late for my period. Been ttc since November. Last period started the 19th of November. But it was only 3 days long. Nervous to test because I have been late before and its been nothing. But I have never been THIS late. Been throwing up for about 2 and a half months. Nipples super sore. Also look pretty bloated and have had weight gain. Opinions please?!
