Mom got headache with me!!!

Since Monday, I've done 4 accidents. Once on Monday and triples on yesterday. On Monday, I peed on the couch. Yesterday on the kitchen floor, living room and on mom's bed when she is taking her bath!!!! Mom gave me a good scold and whack on my butt on Monday and twice yesterday. I never seen her so angry. Coz she already got tonnes of work and she has to work alone with all these things. But on the most serious one, when I peed on her bed, I dashed to my crate when mom came out from the shower. Mom opened wide up her eyes and mouth! No words from her other than tears. She is not angry with me this time. She is worry. She is worry that might it be anything bothering me, making me doing accidents all over. Or is it the medicine that I'm having making me goes moody? But those are only allergic pills. I've been acting very strange too. I didn't play. I didn't run. The only thing normal is I still jump and beg for mom when she's having her meal. hehehe.... So mom straight away called up the vet. Asking is it the medicine bothering me. And yes, the vet said, the medicine would make me slightly sleepy and tired. Mom had a bit of relieve hearing this, but still she is worry coz she is not use to see me so down. This morning when we woke up, mom straight away put me in the toilet for my pee, like what she does when she toilet trained me. Hoping I would get better today. She took out all my toys. Wear me a sweater as the raining weather is quite cooling. She hopes everything would be much more better today.
